Head coach Tom Coughlin said Boley may sit a few more practices.
"He’s got a little hamstring," Coughlin said. "Couple days I'm sure."
Coughlin said Rivers has the same deal.
Defensive end Justin Trattou was in a walking boot on his left foot this morning after spraining his ankle in practice the day before. He was scheduled to undergo an MRI.
Cornerback Terrell Thomas iced down his surgically-repaired right knee for the last quarter of practice and Coughlin said this will probably be a regular routine for him to maintain his knee.
