Clemson defensive end Da'Quan Bowers won't participate in the school's pro day. Bowers, who had arthroscopic knee surgery following the season, is now slated to do on-field work April 1 for those interested, allowing him more time to regain his form. That contradicts the "100 percent" evaluation Bowers gave his knee at the combine, though he did not do on-field work in Indianapolis last month.
