Defensive tackle Sharrif Floyd and offensive lineman David Yankey both left Tuesday night's practice with injuries.

Floyd was injured in the two-minute drill near the end of practice. After one play, he walked toward the sideline before slowly dropping down on all fours. Then athletic trainers surrounded him for a couple of moments before he got up and slowly walked to the sideline.

Floyd, who battled injuries last season, did stand on the sideline for the rest of the practice, giving hope that his injury might be minor.

Yankey slowly walked off the field with head athletic trainer Eric Sugarman early in practice. It is not known when and how he got hurt. After about a half hour or so, Yankey returned the sideline but did not re-enter practice.

In other injury news, outside linebacker Anthony Barr, defensive end Scott Crichton, cornerback Josh Robinson, defensive tackle B.J. DuBose and wide receiver Gavin Lutman all sat out practice with injuries.

Center John Sullivan was absent after the birth of his son earlier today.
