Cooper (biceps) played 38 offensive snaps during Thursday's 33-26 preseason win over the Cardinals.

EDGE Analysis

Cooper appears fully recovered from the biceps issue that landed him on IR last season. The veteran guard could be thrust into the starting lineup to begin the regular season, with Richie Incognito facing a two-game suspension.

Cooper (biceps) signed a contract with the Raiders on Monday, Field Yates of ESPN reports.

EDGE Analysis

The veteran lineman only logged four games last season in Washington before tearing his bicep, resulting in his placement on injured reserve. He suffered the injury in mid-December, which usually has a three-to-four month recovery process. Look towards the beginning of training camp next week to determine where Cooper's health currently stands. If healthy, Cooper will add some veteran presence to the Raiders line -- especially given the looming suspension of Richie Incognito.

Cooper (arm) has been downgraded to out for the remainder of Monday's tilt with the Eagles.

EDGE Analysis

The severity of Cooper's arm injury is still unclear but more details will likely surface following the conclusion of Monday's game. As for now, Luke Bowanko will attempt to fill the void left from Cooper's absence.

Cooper (arm) has been ruled out for the remainder of Monday's contest against the Eagles.

EDGE Analysis

Cooper exited during the first quarter of Monday's game due to arm injury -- look for the details to be smoothed out in the coming days. In the meantime, Luke Bowanko will likely fill in on an already thin offensive line for the Redskins.

Cooper is questionable to return to Monday's game against the Eagles with an arm injury.

EDGE Analysis

Cooper exited the game in the first quarter. With the Redskins thin along their interior offensive line, Luke Bowanko will fill in for Cooper at left guard as long as he is out.

Cooper signed a contract with Washington on Monday.

EDGE Analysis

Cooper's spot on Washington's 53-man roster comes following the placement of starting guards Shawn Lauvao (knee) and Brandon Scherff (pectoral) on injured reserve. The 2013 first-rounder will provide much-needed depth to the Redskins' offensive line, and could slot into the starting rotation during Sunday's matchup against the Buccaneers.

Cooper (knee) was active for Saturday's preseason game against the Colts.

EDGE Analysis

While it's good news for Cooper that he was finally able to get back on the field, the fact that the guard only played 17 snaps Saturday suggests that he'll be eased back into the 49ers rotation up front.

Cooper (knee) has been cleared off the PUP list and will be eligible to return to practice, Cam Inman of the Bay Area News Group reports.

EDGE Analysis

Cooper began training camp on the PUP list as his recovery from an MCL injury remained in progress, but the offensive lineman has progressed enough to return to the practice field.

Cooper (knee) was placed on the Physically Unable to Perform list Wednesday, Joe Fann of the 49ers' official site reports.

EDGE Analysis

Cooper is still in the process of rehabbing an MCL injury that required surgery in January. It isn't clear how long the offensive lineman will be sidelined in training camp, but there at least doesn't seem to be any concern that his absence will extend into the preseason.

Cooper (knee) is expected to remain sidelined until training camp, Eric Branch of the San Francisco Chronicle reports.

EDGE Analysis

Cooper signed with the 49ers in March to fortify the interior of the line, but he continues to recover from surgery in January to repair the MCL in his left knee. The veteran interior lineman is expected to compete for a starting job when healthy, which should arrive in training camp if he can avoid setbacks.
