Former Husky Chris Polk signed a rookie free-agent deal with the Philadelphia Eagles shortly after medical concerns caused the running back to go undrafted.

Polk, who finished his career at Washington second on the school's all-time rushing list, was projected to be drafted as high as the second round. But NFL teams were apparently scared off by one or more of Polk's previous injuries. Mike Mayock of NFL Network said several teams took Polk off of their draft boards due to a "degenerative" shoulder problem.

Polk spoke with NFLDraftScout.com after signing with the Eagles and said he was aware of teams' concerns about his shoulder. He denied a report he said he heard about an additional issue with his hip.

"I will just have to go out there and show them I have a lot of great football left in me," Polk told the website. "I know teams are concerned about my shoulder, but I also heard somebody say something about a degenerative hip and there is just no truth to that. I had labrum surgery on the shoulder a year ago and it didn't slow me down last season."

According to NFLDraftScout.com, Polk had his shoulder examined by renowned orthopedic surgeon James Andrews, who said he only noticed some scarring from a previous surgery but nothing that would affect Polk's ability to play football.

Polk had two shoulder surgeries early in his college career, as well as a knee scope before last season. Despite that, he didn't miss a game from 2009-2011.

According to NFLDraftScout.com, Polk chose the Eagles over the Washington Redskins.
