Rookie safety Phillip Thomas is now walking without the assistance of crutches and has graduated to a protective boot after having surgery to repair a Lisfranc tear earlier this season.

A fourth-round pick out of Fresno State, Thomas suffered the injury in the preseason opener and was lost for the season.

Thomas said on Wednesday that he is expected to be out of the walking boot in roughly three weeks, and then will begin to ramp up his rehabilitation activities soon resume running.

“I’m excited. I’ll be able to start doing more stuff soon,” Thomas said.

Thomas has been receiving treatment at Redskins Park all season. He attends some meetings and film-study sessions.

Although disappointed to have missed his rookie season, in which the Redskins have experienced a fair amount of turmoil at the safety position, he is optimistic that he will be back to full speed well before the offseason conditioning program begins in 2014, and then he can begin laying the groundwork for a promising first full season.
