A pair of key offensive players for the Chicago Bears are unavailable until further notice.
Tight end Zachary Miller and receiver Eddie Royal are both in the NFL’s mandated concussion protocol, the Bears announced.
Miller practiced Sunday -- and even spoke to the media at the Olivet Nazarene dining hall -- but later experienced delayed symptoms that he reported to the team.
Royal briefly participated in Monday’s practice before he went back to the locker room.
Both are important members on offense. Miller, the Bears’ No. 1 tight end, enjoyed a breakout year in 2016 with 34 receptions for 439 yards and five touchdowns. Royal is the team's slot receiver with Alshon Jeffery and Kevin White on the outside.
