BOURBONNAIS, Ill. -- Pro Bowl wide receiver Alshon Jeffery suffered a minor AC joint sprain on Sunday but managed to finish practice, Chicago Bears head coach John Fox announced.

Jeffery, who is only under contract through 2015, is the favorite to assume the No. 1 wide receiver role previously occupied by Brandon Marshall.

In three years with Chicago, Jeffery has 198 receptions for 2,921 yards and 20 touchdowns over 42 games (36 starts). He became only the fourth player in franchise history to record consecutive 1,000-yard receiving seasons and has eight career 100-yard receiving games. Jeffery was not entirely healthy for much of 2014, but ranked in the NFL's top 15 in receiving touchdowns, receptions and receiving yards.

“I’ve liked what he’s done and like the way he competes,” Fox said. “He’s got a big wingspan and a big ball radius as far as plucking catches away from defenders. I’ve liked what I’ve seen.”

In other injury news, defensive end Jarvis Jenkins temporarily left the practice field Sunday to have a dislocated finger popped back into place. Jenkins was back on the field by the time practice ended.

Fox also disclosed that quarterback David Fales is recovering from the illness that landed the second-year QB on the non-football injury (NFI) list.

“It’s an illness where the doctors don’t want him moving around a whole bunch until he heals,” Fox explained. “I can’t predict exactly when he is going to be out there but he’s progressing as expected.”

The Bears next practice Monday at 9:35 a.m. CT before an off day on Tuesday.
