Chris Heisey (hamstring) is set to begin a minor league rehab assignment Friday at Triple-A Louisville.

Heisey will spend the entire weekend in Kentucky before returning to the Reds' active roster early next week. He has been on the disabled list since April 27 with a severe right hamstring strain and should take over starting left duties almost immediately upon returning.

Chris Heisey (hamstring) is able to sprint at full speed.

Heisey hit on the field Thursday and will do so again on Saturday. It's not clear when he'll begin a rehab assignment, but he's getting "close." The 28-year-old outfielder has been sidelined since April 27 with a strained right hamstring.

Chris Heisey (hamstring) is unsure when he'll resume a rehab assignment.

Heisey is with the Reds on their road trip, but he hasn't been told when he'll start playing in rehab games again. "I haven't heard anything," Heisey said. "I feel good though." The outfielder was able to run at about 80 percent effort over a week ago, so he can't be too far off.

Reds trainer Paul Lessard said Wednesday that Chris Heisey (hamstring) is able to job at about "80 percent effort."

Heisey landed on the disabled list in late April due to a hamstring strain and aggravated the injury during a rehab assignment last week. His absence is expected to stretch into June.

The Reds have determined that Chris Heisey's hamstring aggravation was not severe.

"It wasn't horrendous," assistant general manager Bob Miller said. "He tweaked it." Heisey won't return until the next homestand, which runs from May 24-28, at the earliest. It's certainly possible his absence could stretch into June.

Chris Heisey re-strained his right hamstring on Monday night at Double-A Pensacola and has been pulled off his minor league rehab assignment.

Heisey will head to Cincinnati to be evaluated by team doctors. He had been aiming to return to the Reds this week but could now struggle to make it back before the end of May. The outfielder has been on the disabled list since April 27.

Chris Heisey left Monday's rehab game with Double-A Pensacola with discomfort in his hamstring.

Heisey, who was rehabbing a strained oblique, suffered the injury while making a shoestring catch in the first inning. The Reds should have an update on his status on Tuesday, but it appears his return will be pushed back.

Chris Heisey (oblique) left his first rehab game on Monday with Double-A Pensacola for precautionary reasons.

Heisey was originally scheduled to play seven innings, but he left after he made a shoestring catch to end the top of the first inning. "I don't think he re-aggravated it, but I just didn't like the way he was moving and there is no reason to push that," said Pensacola manager Delino DeShields. "We are going to be as careful as we can with him. He probably won't play (tonight) and we'll see how it goes from there." The Reds were hoping Heisey would be ready to return by Friday, but his timeline will likely be pushed back now.

Chris Heisey (hamstring) is slated to be activated from the disabled list on Friday.

Heisey will begin a short rehab assignment with Double-A Pensacola on Monday. "I'm feeling great, rehab is going well," Heisey said on Saturday. "The training staff has done a great job and walked me through it. I'd never hurt my hamstring before, it's a new thing for me. Feeling really good now."

Chris Heisey (hamstring) will begin a minor league rehab assignment Saturday with Double-A Pensacola.

He'll likely only need a handful of at-bats before being activated. The 28-year-old has been sidelined since April 27 due to a strained right hamstring. He should get the bulk of the playing time in left field upon his return.

Chris Heisey (hamstring) has been jogging and hitting.

He's yet to do any running, but Heisey said that doesn't mean the hamstring isn't getting better. "I can't come off the DL for a week," Heisey said. "There's no reason to test it now. It feels good. Every day I've been able to go a little faster."

Reds placed OF Chris Heisey on the 15-day disabled list, retroactive to April 27, with a right hamstring strain.

Heisey suffered the injury during Saturday's loss to the Nationals and will likely need at least 2-3 weeks of down time. The Reds will call up Donald Lutz to provide some depth while Heisey is sidelined.

Chris Heisey (hamstring) is expected to be placed on the disabled list.

Heisey won't be placed on the DL Sunday, but that's only because his roster replacement, Donald Lutz, couldn't arrive in time for the game against the Nationals. The outfielder suffered a strained right hamstring Saturday and needs at least a couple weeks of down time.

Chris Heisey left Saturday's game against the Nationals with a strained right hamstring.

The Reds are saying that Heisey was removed for precautionary reasons, but it's very possible that he could need a stint on the disabled list. Xavier Paul has replaced him in left field.

Chris Heisey went 0-for-4 and grounded into a double play Wednesday against the Cardinals.

Manager Dusty Baker probably isn't going to need much of an excuse to give Zack Cozart a try in the two hole over Heisey. Filling in for Ryan Ludwick in left field, Heisey is hitting .167 with a homer and two doubles in 31 at-bats. He also has an 11/1 K/BB ratio. He probably won't lose his starting job right away, but he could well be dropped to seventh in the lineup.

Chris Heisey singled in a run and also belted a three-run homer Tuesday against the White Sox.

It should be noted that the dinger came off of John Danks, who has looked woeful this spring, but it's a nice day for Heisey nonetheless. He's batting .293 with three homers this spring and should play more than your average fourth outfielder this season.

Reds manager Dusty Baker said Saturday that he likes having Chris Heisey serving in the fourth outfielder role, and that he's a very valuable piece to the team.

Baker noted that injuries happen. Ryan Ludwick, Shin-Soo Choo and Jay Bruce are locked into the starting spots, but Heisey will see plenty of playing time in 2013.
