Mike Shanahan mulls sitting RG III

— -- Mike Shanahan is still the coach of the Washington Redskins, but Robert Griffin III might not be the starting quarterback this week.

Shanahan said Monday that he was thinking about sitting Griffin for the rest of the season because of concern that the quarterback could be injured.

Shanahan pointed out that Griffin has been sacked 24 times in five games, and that two of the Redskins' three remaining games will be played on artificial turf, including Sunday at Atlanta.

It's a change of pace of Shanahan's previous stance that Griffin needed as many game snaps as possible to improve.

Shanahan no longer spoke as if it's a given that he'll be coaching the Redskins next season. He says team owner Dan Snyder will make that decision at the end of the season.

He said he had spoken to Snyder but refused to reveal the details of their conversation. He did say he believes he has a good relationship with the owner. 

Shanahan again refused to comment on ESPN's report that he was prepared to resign at the end of last season but changed his mind after Griffin suffered his knee injury in a playoff loss to the Seattle Seahawks.
