A league source has confirmed the AnnArbor.com report that Eagles defensive end Brandon Graham underwent microfracture surgery on his right knee last December.
Graham tore the anterior cruciate ligament in the knee Dec. 13 against Dallas. In March head coach Andy Reid said it would be a real stretch for Graham to play in the Eagles season opener at St. Louis on Sept. 11, assuming the regular season starts as scheduled.
The Eagles expect Graham to return by the middle of the season, and on Wednesday he tweeted with confidence.
"I am not doing interviews with nobody until I'm back on the field. Everybody needs to worry about this lockout if anything. I got this!!"
Graham, the teams first-round pick in last years draft, started the first four games of last season before losing his starting job to veteran Juqua Parker. He started two more games late in the season when Parker was out with an injury before getting hurt in Dallas.
Defensive end Victor Abiamiri had microfracture surgery in February of last year and did not play last season.
