Washington Redskins tackle Trent Williams practiced Monday and has been fully cleared after being taken to the hospital in an ambulance following the team’s game at Dallas on Thanksgiving Day. Williams said the medical staff was worried he had suffered a bruised liver in the team’s 31-23 loss to the Cowboys, but that wasn’t the case. He had a bruised rib diagnosed. “I was a tad bit dehydrated, so I was a little lightheaded and stuff,” Williams said. “They just wanted to be safe [rather] than sorry.” The six-time Pro Bowl selection also said his surgically repaired thumb is a challenge to play with, considering the cast virtually takes away the use of his right hand. The cast immobilizes the joint, but keeps him from grabbing while blocking. He also experiences pain from impacts while blocking. The Redskins were able to get an extra workout in this week, with their next game coming next Monday night in Philadelphia. Cornerback Quinton Dunbar (shin), linebacker Zach Brown (knee), defensive lineman Jonathan Allen (knee), defensive lineman Matt Ioannidis (calf), linebacker Ryan Anderson, linebacker McKinzy Cassanova, tackle Morgan Moses (ankle), and tight ends Jordan Reed and Jeremy Sprinkle did not participate during the portion of practice open to the media.
