Best chance for Khalil Mack's return yet; Allen Robinson finishes full practice

The Bears' sick bay crowd took on a much lighter look.

The Bears injury report took on a different look for the first time in four weeks, because their headliner was back.

Khalil Mack went through a full practice Wednesday for the first time since his Oct. 14 ankle injury against Miami. His availability Sunday will depend on how he responds to the injury the rest of the week at practice.

Also back full time was wide receiver Allen Robinson for the first time since sitting out the last two games due to a groin injury.

Tight end Adam Shaheen went through a full practice Wednesday for the first time since suffering a foot injury in preseason. The Bears will decide later in the week whether to activate him.

"We’re looking forward to Adam being back," quarterback Mitchell Trubisky said. "Me and Adam have a great connection from last year; obviously a big target and runs good routes for his size and can separate.

"He’s just a mismatch problem across the board for linebackers and safeties, and when you get a corner on him as well, his size is just too much to handle. Getting him back’ll just open things up even more for this offense and he’s another option for this option to be even more dynamic.”

Shaheen is 6-foot-6, 278 pounds and can be an asset also as a blocker, with tight end Dion Sims out Wednesday due to a concussion.

It could be like a new toy for coach Matt Nagy if Shaheen fits into the offense, particularly in the red zone. Nagy said Shaheen was just starting to make an impact when he suffered a foot injury.

"I thought that he was coming on, he at that point in time was still digesting the playbook but you saw some things that he was doing," Nagy said. "He was getting the ball a little bit and he's a nice-sized guy, so one-on-one battles he does well with. But he was also learning how to play tight end and how to runs some of the routes that we run in this offense.

"So it was tough to see him go down the way that he did because I thought that he was really one of those guys that was progressing pretty fast. So it'll be exciting to get him back out there and see exactly where he's at."

Guard Eric Kush (neck) and tight end Ben Braunecker (concussion) are also past their injuries and went through full practices.

Wide receiver Taylor Gabriel, who appeared in the last game to aggravate a knee injury he'd been battling since earlier this season, practiced Wednesday on a limited basis.
