Cooper (toe) is active Monday against the Chargers, Mark Dalton of the Cardinals' official site reports.

Cooper was dogged by turf toe throughout the preseason. However, even though he's active, he'll back up Ted Larsen at left guard, leaving his first NFL snap up in the air.

Cooper (toe) is expected to practice Monday, AZCardinals.com reports.

Cooper's nagging turf toe injury kept him sidelined for Sunday's third preseason game, which allowed Ted Larsen to start at left guard. While Cooper is slated to return to practice Monday, the former first-rounder is no certainty to start this this season and will have to prove himself leading up to Week 1.

Cooper continues to be sidelined by a nagging bout with turf toe, the Cardinals' official site reports. "It's getting better each day, but it hasn't gotten to the point where I feel I can be effective and really evaluated fairly," he said.

Because Cooper occasionally breaks technique and plays on his toes, the injury is particularly bothersome. As a result, he'll yield left guard to Ted Larsen on Sunday against the Bengals. Consider Cooper day-to-day, but if his absence continues unabated, Larsen could hold onto the gig for good.

Cooper, who had his knee drained Wednesday, will play in Saturday's preseason opener against the Texans, Kent Somers of the Arizona Republic reports.

Cooper missed practice Tuesday due to soreness in the knee, which was alleviated following the procedure and allowed for more ease in his movements. In any case, he'll continue to split time at left guard with Earl Watson due to Cooper's slow start to training camp.

Cooper has split left guard reps with Earl Watford in recent practices, the Arizona Republic reports. Coach Bruce Arians stated that the timeshare will be status quo going forward.

Additionally, Arians expressed disappointment with Cooper's footwork in particular. While Cooper's balance contributed to his selection at seventh overall in the 2013 NFL Draft, the broken left fibula that he sustained near the end of last preseason has altered his approach, resulting in far too many plays on the ground. His fight for a starting gig will officially commence Saturday in the Cardinals' preseason opener against the Texans.

Jonathan Cooper (leg) has taken "all" the snaps at left guard in Cardinals OTAs.

Coach Bruce Arians said Cooper isn't quite 100 percent, but it's extremely good news that he's healthy enough to man his position in voluntary workouts. The No. 7 overall pick of last year's draft, Cooper missed his entire rookie year with a fractured left fibula. The Cardinals need Cooper to help turn around one of the league's worst run-blocking lines.

Cardinals GM Steve Keim fully expects LG Jonathan Cooper (fractured left fibula) to be ready for OTAs.

Cooper has progressed without setbacks since going down in August. A full offseason will serve him well after missing his entire rookie campaign. The Cardinals had one of the league's worst run-blocking lines last season, and will be counting on Cooper to help turn it around.

Cardinals LG Jonathan Cooper (fractured left fibula) has resumed jogging and says he's on track to be ready for OTAs.

Cooper fractured the leg in an August 24 preseason game and missed his entire rookie year. The seventh overall pick in the 2013 draft, Cooper's return will give the Cardinals' offensive line a huge boost. Arizona is expected to have a 2014 interior trio of LG Cooper, RG Daryn Colledge, and C Lyle Sendlein.

Cardinals placed LG Jonathan Cooper on injured reserve with a fractured fibula, ending his season.

They're apparently not using I.R./designated for return. Cooper was the seventh overall pick in April's draft and was likely to be the Cardinals' best offensive lineman this year. Don't expect many running lanes in the desert this season for Rashard Mendenhall and rookie Stepfan Taylor.

The Cardinals are holding out hope first-round LG Jonathan Cooper (fractured fibula) can play later this season.

Per coach Bruce Arians, Cooper's "best case scenario" would be to return in 10-12 weeks. Arians would love for Cooper to play "the last six games or so," because the Cardinals "don't want him to be a rookie again next year." Cooper is a prime candidate for Arizona's injured reserve/designated for return spot.

Cardinals rookie LG Jonathan Cooper suffered a fractured left leg in Saturday night's preseason game.

Cooper is very likely looking at a season-ending injury, but hasn't been ruled out as a candidate for injured reserve/designated for return. Regardless, it's a massive downgrade to an already weak offensive line and means that the Cardinals will be forced to start Chilo Rachal or move one of Levi Brown or Bobby Massie to left guard. Cooper was the seventh overall pick in April's draft.

ESPN's Chris Mortensen reports the Cardinals are "nervous" about a lower-left leg injury suffered by rookie LG Jonathan Cooper Saturday night.

Cooper was carted off after getting his left leg rolled up following a downfield block. He's already the Cardinals' best lineman, and losing Cooper for any amount of regular season time would be an enormous blow to an otherwise weak blocking group. Cooper was the seventh overall pick in April's NFL draft.
