As they recovered from injuries last week, outside linebacker Khalil Mack (ankle) and receiver Allen Robinson II (groin) practiced on a limited basis Friday after sitting out Wednesday and Thursday.

Asked about their participation in practice this week, coach Matt Nagy said Wednesday that it would be "very similar" to last week. At this time, it's not known whether Mack and Robinson, who sat out last weekend's win over the Jets, will play Sunday when the Bears visit the Bills in Buffalo.

Mack injured his ankle against the Dolphins Oct. 14 in Miami. In four previous games, he recorded five sacks and four forced fumbles and returned an interception for a touchdown, earning NFC defensive player of the month honors for September.

Playing hurt against the Dolphins and again the following week versus the Patriots, Mack did not register a sack or generate a takeaway. When the Bears hosted the Jets last Sunday, he missed his first game in five NFL seasons.

"Hopefully he's getting better," Nagy said Wednesday. "I feel like he is."

Robinson, meanwhile, exited the Patriots game in the second half after aggravating his groin injury. In his first season with the Bears, he has caught 25 passes for 285 yards and two touchdowns.
