Quick hits from coach Mike Shanahan’s briefing after Tuesday’s practice:

Shanahan expects it to take another two or three days for Ryan Kerrigan to return to practice. The team continues to hold him back for precautionary reasons.

The Redskins have agreed to terms with Rex Grossman and he will be at Redskins Park Tuesday night.

Tim Hightower didn’t practice because he was a restricted free agent with Arizona and can’t be on the field until Aug. 4th.

Shanahan admitted that John Beck didn’t look as sharp today and said he might be getting too many reps because of Grossman’s absence.

Shanahan said Phillip Buchanon has been suspended for the first four games. He wouldn’t say why the league suspended the cornerback, but said the ruling came “a while back.”
