WR Keenan Allen won't work out

California's Keenan Allen, projected as one of the top two wide receivers in the upcoming draft, is nursing a sprained posterior cruciate ligament that will prevent him from working out at the combine, his agent, JT Johnson, said Wednesday.

Allen will attend the combine and undergo medical exams for the teams, but with his knee being only 70 percent, he and Johnson have decided it is better not to run. Allen will save his running for his own pro day sometime in early April after he has recovered. He initially suffered the knee injury Oct. 20, then aggravated it about two weeks ago while training for the combine in Florida with Hall of Fame wide receiver Cris Carter. One doctor told Allen he tore his posterior cruciate ligament.

Allen then visited Dr. James Andrews, who told Allen and Johnson in his report to them, "I do not feel this would require surgical intervention."

Allen now plans to let the injury heal on his own. He also will run routes at Cal's pro day on March 14, but he will not do the bulk of his testing until he has more time to heal in early April. Allen is the latest player to pull himself out of some combine drills, joining USC quarterback Matt Barkley and Alabama running back Eddie Lacy.
