Nagy, 39, leaves K.C. to be Bears’ coach

The Chicago Bears hired Kansas City offensive coordinator Matt Nagy as their head coach Monday, hoping he can help a floundering franchise emerge from one of the worst runs in its history.

The Bears announced the move a week after firing John Fox, who went 14-34 in three seasons for a .292 winning percentage, the second-worst in team history. The Bears were 5-11 this season and haven’t finished above .500 since they let Lovie Smith go following a 10-6 finish in 2012, two years after their last visit to the playoffs.

Nagy, 39, spent the past 10 seasons working under Andy Reid in Philadelphia and Kansas City. He did not call plays until late this season, but drew praise for his work with quarterback Alex Smith. In Chicago, Nagy will try to develop No. 2 overall draft pick Mitchell Trubisky.

The Chiefs won the AFC West, only to blow an 18-point halftime lead in a playoff loss to Tennessee on Saturday. The Bears met with Nagy on Sunday and wasted little time hiring him.

If protocol was not properly followed, the team is subject to discipline, including a $150,000 fine.

Newton spent time on the ground after the hit. Then, as he walked toward the sideline, he appeared to stumble to one knee. He briefly pointed toward his right eye. He sat out one play, but returned on the next series and finished the game.
