F Amir Johnson.scored 19 points, grabbed eight rebounds and added four assists, three steals and three blocked shots Friday."You could see it in our shoot-around -- he was going a hundred miles an hour in our 4:15 shoot-around, so you could tell he was locked in and engaged," coach Brad Stevens said.Johnson, who signed a two-year free-agent contract with the Celtics, was coming off a three-game stretch that saw him score just 16 points and grab 15 rebounds in over 55 minutes. He took only 12 shots in the three games and was averaging 7.7 points and 5.7 rebounds in his first seven games in his new uniform.Friday night, he scored Boston's first five points and had seven in the first quarter. His assault on the boards helped the Celtics (4-4) pile up a 50-35 rebounding advantage, 17-5 on the offensive boards. That is how you take 103 shots (hitting 42, 11 of them 3-pointers) in a game."I try to find a way every game to bring some energy," Johnson said.

F Amir Johnson started Friday night despite tweaking an ankle on Wednesday night.

F Amir Johnson, who left the Raptors for Boston as a free agent, had 11 points and eight rebounds in his first game against his old team Friday.

F Amir Johnson, making his Celtics debut, came off the bench to contribute 15 points and seven rebounds in the opener Wednesday.

Johnson returned to practice Sunday after sitting out with an illness, Gary Washburn of the Boston Globe reports.

The Celtics as a whole have been dealing with a flu bug, which has caused a few different players to miss time. Johnson sat out Thursday's matchup with Real Madrid because of it, but is feeling better and was able to return to practice Sunday. With three more days of rest until Wednesday's game against the Nets, there's no reason to think Johnson won't be able to suit up and play.

Johnson missed Thursday's exhibition against Real Madrid, Adam Himmelsbach of the Boston Globe reports.

A bug has been working its way around the Celtics locker room recently, so it's possible Johnson will be isolated from the team for a few days until he shows improvement with his condition. The illness shouldn't jeopardize Johnson's availability for the majority of what remains of the Celtics' preseason schedule, but the big man's chances of opening the regular season in a starting role appear to have dissipated. Coach Brad Stevens has used David Lee and Tyler Zeller as his starting frontcourt for both of the Celtics' exhibitions thus far, leaving Johnson, Jared Sullinger, Kelly Olynyk, and Jonas Jerebko to fight for reserve minutes.

Johnson signed a two-year, $24 million deal with the Celtics on Wednesday, Sam Amick of USA Today reports.

The 28-year-old will accept a short-term deal with his sights set on hitting free agency again in two summers when the cap is expected to be significantly higher. Johnson averaged 9.3 points and 6.1 rebounds in 26 minutes for Toronto last season, and he'll compete for a starting spot in the Celtics' frontcourt.

Johnson averaged 9.3 points (57% FG, 41% 3Pt, 61% FT), 6.1 rebounds, 1.6 assists, 0.6 steals, and 0.8 blocks in 26 minutes per game during 75 regular season game in 2014-15.

The 28-year-old hard-nosed forward may have played his final game with the Raptors, who could opt for a shakeup this summer after being swept by the Wizards. In four playoff games Johnson contributed 11.5 points (69% FG, 0% 3Pt, 50% FT), 7.0 rebounds, 1.0 assist, 0.3 steals, and 0.8 blocks in 28 minutes per game.

Johnson grabbed a double-double with 14 points, 12 rebounds, three assists, one steal, and one block in 33 minutes of action in Game 3 against the Wizards.

Johnson has been fairly consistent in the Playoffs, averaging 14.0 points and 8.3 rebounds so far. He'll have a chance to help the Raptors avoid a sweep in Game 4 at Washington.

Johnson will start in Friday's Game 3 against the Wizards.

Johnson has scored in double-digits through the first two games of the series and is getting the reward of a spot in the starting lineup over Tyler Hansbrough as a result. Although, Johnson was already averaging 26.4 minutes in those two games so his role on the court may end up being somewhat similar as in Games 1 and 2.

Johnson is expected to have a large role in Tuesday's Game 2 against the Wizards, Josh Lewenberg of TSN Sports reports.

Johnson came off the bench in Game 1 but still led his team with 18 points Saturday. Coach Dwane Casey admitted that he may switch up his rotation for Game 2, although the coach does expect Johnson to play around 34 minutes like he did in Game 1. If for some reason Johnson is moved into the starting lineup then James Johnson would likely be the unfortunate party who moves to the bench.

Johnson led the Raptors with a team-high 18 points (8-12 FG, 0-1 3Pt, 2-3 FT), eight rebounds, one assist, and one block in 34 minutes during Saturday's Game 1 loss to the Wizards.

Johnson came off the bench, giving his coach cause to start him in Game 2 on Tuesday. He took advantage of the Wizards' smaller lineup, scoring all his points inside of seven feet or at the foul line.

Johnson will come off the bench in Game 1 on Saturday, the Toronto Star's Doug Smith reports.

The Raptors will continue to roll with Tyler Hansbrough with the starters, but Johnson still figures to be prominently involved off the bench.

Johnson (ankle) provided eight points (4-5 FG) and eight rebounds in 16 minutes in the loss to Boston on Tuesday.

Johnson returned from a four-game absence and played limited minutes off the bench. To have success in the playoffs, the Raptors will need Johnson to be effective. The 6-9 forward has been a steady presence in the Raptor frontcourt over the past three seasons.

Johnson (ankle) will play in Tuesday's game but he will come off the bench, the Toronto Sun's Mike Ganter reports.

Considering this is the first game of a back-to-back to finish the season, it would not be surprising if the Raptors held Johnson out Wednesday. Tyler Hansbrough gets the start Tuesday.

Johnson (ankle) is considered questionable for Tuesday's game, Josh Lewenberg of TSN reports.

Johnson said his ankle is nearing 100 percent and noted that if the playoffs started Monday, he would be playing. However, the team will continue to treat the situation with caution, and they'll wait until Tuesday to rule Johnson in or out. Tyler Hansbrough has started the last four games in Johnson's place.

Johnson (ankle) is out Saturday, but if it was a playoff game, he would take the court, the Toronto Sun reports.

Johnson put in a full workout in pregame warmups both Friday and Saturday, but the Raptors are merely exercising caution to ensure he's as healthy as possible for the postseason. In his place, Tyler Hansbrough is once again getting the nod at power forward.

Johnson (ankle) won't suit up Saturday at Miami, the Miami Herald reports.

Johnson is missing his fourth game in a row due to a right ankle sprain. In his stead, Tyler Hansbrough could very well garner another start. Johnson's next chance to play will arrive Tuesday in Boston.

Johnson (ankle) will not be inserted in Friday's game against the Magic, Ryan Wolstat of the Toronto Sun reports.

Johnson should be considered day-to-day moving forward as he looks to rest his oft-injured ankle ahead of the playoffs. His next opportunity to make a return will be against the Heat on Saturday.

Johnson (ankle) went through a full shootaround Friday but remains unlikely to play against the Magic, Ryan Wolstat of the Toronto Sun reports.

The Raptors will be careful with Johnson, who's missed the last two games, as they goal, of course, is to have him healthy for the playoffs. He'll likely rest another game or two before returning to action. The Raptors are in Miami on Saturday before heading to Boston on Tuesday. They then finish out the season at home Wednesday against Charlotte.
