The Facts: A pair of key offensive players for the Chicago Bears are unavailable until further notice. 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 -- but later experienced delayed symptoms that he reported to the team. "He felt a little funny last night and didn't feel as good this morning, so we just shut it down," HC John Fox said. "He'll go through the NFL's concussion protocol."

Diehards Line: 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, 30, is one season removed from catching 62 balls for 778 yards and seven touchdowns for the San Diego Chargers. Royal, who had 37 receptions for 238 yards and a score in his first season with the Bears, battled injuries much of last year but is still one of Chicago’s top three targets at wide receiver.
