LAKE FOREST, Ill. -- A lingering foot injury kept starting right tackle Jordan Mills off the practice field Friday -- forcing the Chicago Bears to list Mills as questionable to face the New England Patriots on Sunday.

Mills went backwards on the injury report the entire week; downgraded to limited participation in practice on Thursday (Mills had full participation on Wednesday) before sitting out Friday's session altogether.

“It’s a problem [Mills’ foot injury] right now and we’ll have to see how it is over the course of the next couple of days,” Bears head coach Marc Trestman said. “We’ll have to see where Jordan is. If he can’t go, then Michael [Ola] will be in his place [at right tackle].

Ola started three games at left guard and two games at left tackle earlier in the season when Matt Slauson and Jermon Bushrod were injured.

Meantime, linebackers Jon Bostic (back) and Lance Briggs (ribs) are both listed as doubtful for Week 8. Trestman said Briggs is still dealing with soreness but is making progress towards an eventual return.

In more encouraging news, rookie cornerback Kyle Fuller is probable for Sunday after suffering a broken right hand and right hip pointer injury last weekend in the loss to the Miami Dolphins. Fuller has worn a protective brace on his hand the past two days at practice, but it’s unknown if he plans to wear anything on his hand versus New England, according to Trestman.

Safety Chris Conte (shoulder), defensive tackle Jeremiah Ratliff (non-injury related) and tight end Martellus Bennett are also probable.

Safety Danny McCray has been ruled with a knee injury.
