"So, that's a good sign," Harbaugh said. "It gives him a chance certainly for this week."
Forsett hurt his ankle late in the fourth quarter of Sunday's 33-30 overtime loss to the Cleveland Browns. He walked off the field on his own power, but he didn't play in overtime.
Forsett said he didn't return to the game because he was worried about causing more damage to his ankle. He was injured while being tackled by Browns safety Donte Whitner on a 32-yard catch.
After the game, Forsett didn't walk with a limp in the locker room. Forsett and backup running back Lorenzo Taliaferro (foot), who was inactive Sunday, both could be limited throughout practice this week.
