Chicago -- The Detroit Lions will have four running backs active against the Chicago Bears on Sunday, but just two tight ends. 

The Lions announced rookie running back Kerryon Johnson is active for the contest despite entering the day questionable with an ankle injury. The recently re-signed Zach Zenner is also active. 

Tight end Luke Willson was scratched after being limited with a shoulder injury this week, leaving the team with just Michael Roberts and Levine Toilolo at tight end. 

Willson has appeared in all eight games for the Lions this season, including five starts. His 263 offensive snaps lead the position group by a wide margin. 

Also inactive for the Lions are guard TJ Lang, cornerback Darius Slay, wide receiver Bruce Ellington, offensive tackle Andrew Donnal and linebackers Eli Harold and Jalen Reeves-Maybin.

Lang, Slay and Harold had been previously ruled out. Reeves-Maybin was questionable with a neck injury.
