Daniel Jeremiah reports that Sam Bradford's agent Tom Condon sent out a letter to all 32 NFL teams stating that the Oklahoma QB will not participate in workouts at the NFL Combine next week. This isn't a huge surprise, given the injury that Bradford suffered; he will also skip the Oklahoma Pro Day in early March, but will workout for teams on March 25 on his personal pro-day.
Likewise, NFL Network is reporting that Notre Dame QB Jimmy Clausen will skip workouts at the Combine as well, due to his toe. That is probably a bit of a cop out, since he played half the year effectively with the same toe injury, but his stock can really only go down with a poor workout, but not improve with a great one. He will most likely throw at his Pro Day.
