Colts' Addai could be in line for bigger work load

Addai We won’t get the Colts injury report for awhile still, but Jim Caldwell said before practice Friday that if rookie running back Donald Brown (shoulder) is out, Joseph Addai can expect more carries against San Francisco Sunday.

“What we do with them is let Joe take as many of [the snaps] as he wants, and when he wants to come out of there, we relieve him at that time,” Caldwell said. “So, we’ll go through pretty much the same format, but I would anticipate that his load might be a bit heavier.”

Brown’s done better than Addai in terms of yardage this season -- averaging 4.6 yards a carry to Addai’s 3.3 but getting only about half as many carries.

The Colts are 27th in rushing offense in the NFL while the 49ers are sixth in rush defense.

Chad Simpson and Mike Hart are Indianapolis’ extra running backs.

Caldwell said playing time for Hart is “a possibility,” complimenting his work in practice and saying he’s ready.
