Washington's Chris Polk has been one of college football's most productive players in the last few years, featuring as the Huskies' lead runner and punishing opponents with his strength and speed. But injury concerns made him an unlikely 2012 NFL Draft pick, and after being passed up 253 times, Polk has signed with the Philadelphia Eagles as an undrafted free agent, according to a report.
Polk's injury concerns were largely about a shoulder injury that he has played with throughout his career, as well as a knee injury prior to the 2011 season that required arthroscopic surgery.
