Redskins Head Coach Bill Callahan and Offensive Coordinator Kevin O'Connell spoke to the media today. Callahan gave several injury updates heading into this weekend's game against the Jets. Paul Richardson is dealing with a hamstring injury from the Bills game two weeks ago. He hasn't practiced all week, and this could be an opportunity for rookie Kelvin Harmon to get more playing time. Adrian Peterson is a machine. Vernon Davis is getting closer to returning from his concussion, but Chris Thompson is still dealing with turf toe.
