RENTON, Wash. -- Here's a list of who didn't show up Tuesday, who didn't practice, who did and why on the first day of organized team activities for the Seattle Seahawks:

Bennett, Irvin and Lynch are no shows -- First, these OTA practice sessions are voluntary, but everyone was wondering if defensive end Michael Bennett and linebacker Bruce Irvin, both of whom have issues with their contracts, would elect to skip the workouts. So far, the answer is yes. Oh, running back Marshawn Lynch also wasn't at practice, but that's nothing new. He never attends OTAs.

Wilson, Graham and Avril absent due to family losses -- Tight end Jimmy Graham's mentor and manager, Tammy Meyerson, passed away Friday. Quarterback Russell Wilson flew to Florida to support Graham and attend Meyerson's funeral Tuesday. Defensive end Cliff Avril's father passed away three days ago.

Kam and Sherman full speed -- Strong safety Kam Chancellor and cornerback Richard Sherman, who played in the Super Bowl with significant injuries, were full part participants Tuesday, which was a bit of a surprise. Chancellor suffered a torn MCL the week of the Super Bowl, but still played the entire game. He elected not to have offseason surgery. “I feel great,” Chancellor said. “I feel fast and feel strong. I feel better than any year at this time. This first time I've gotten to train and didn't need any surgeries.” Sherman suffered a torn elbow ligament in the NFC Championship Game last season, but also played the entire Super Bowl. He elected not to have Tommy John surgery in the offseason.

Thomas, Mebane among players who didn't practice -- Free safety Earl Thomas, who had offseason shoulder surgery, and defensive tackle Brandon Mebane, who suffered a torn hamstring last season, were on the field but did not practice. Carroll believes both players could be ready by training camp. Wide receiver Paul Richardson was at practice watching. He's still recovering from ACL surgery. Cornerback Tharold Simon, who had offseason shoulder surgery, also watched practice. Defensive tackle Tony McDaniel didn't practice but Carroll didn't know his injury and said he'll be fine. Wide receivers Chris Matthews and Kevin Norwood were on the field but didn't practice. Carroll said both players could return later this week. Tight end Anthony McCoy, who missed last season after tearing an Achilles tendon, did not practice.

Turbin and Lane rehabbing elsewere -- Running back Robert Turbin and nickelback Jeremy Lane were not at practice because both men still are rehabbing offseason surgeries. Turbin had hip surgery a few weeks ago and Lane had arm and knee surgery from his injuries in the Super Bowl. Carroll said Tuesday that Lane still has some issues to take care of with his arm, which was a compound fracture, and it will take longer to heal than expected.
