(Renton, WA)  --  There's a report that the Seattle Seahawks could have to forfeit a second-round draft pick because head coach Pete Carroll failed to list cornerback Richard Sherman's knee problem on a team injury report during the season.  Carroll revealed early this week that Sherman was dealing with an MCL injury for the second half of the campaign.  ESPN's Chris Mortensen reports that because Sherman never missed playing time during the season, the team feels it shouldn't be severely punished.  The Seahawks are cooperating with the league's investigation.
