Bears Pro Bowl alternate nose guard Eddie Goldman exited Sunday night's game during the first defensive series with a concussion.
Goldman entered the blue medical tent early in the first quarter prior to being escorted very slowly by trainers to the locker room and ruled out for the night.
A key cog in the NFL's No. 6 run 'D,' Goldman 25, started 31 consecutive games prior to Sunday and received his first Pro Bowl recognition this season, his fifth since the Bears selected him in the second round in the 2015 draft.
The Bears, who were eliminated from playoff contention at Lambeau Field last Sunday, trail the AFC West champion Chiefs 10-3 midway through the second quarter. Patrick Mahomes led an 82-yard TD drive on the Chiefs' first possession, converting two third-and-long situations prior to scoring himself from 12 yards out after ROLB Leonard Floyd vacated his edge to cover Pro Bowl TE Travis Kelce.
The Chiefs tacked on three on their next possession, capped by a 56-yard Harrison Butker field goal.
