Khalil Mack's season is over.
The Chicago Bears outside linebacker has been placed on injured reserve and will have season-ending surgery on his foot, according to the NFL Network's Ian Rapoport.
Mack has been dealing with a foot injury through the first eight weeks of the season and missed an Oct. 31 matchup against the San Francisco 49ers because of the ailment.
The six-time Pro Bowler has been dominant for the Bears this season, leading the team with six sacks, one fumble recovery, 19 tackles, six tackles for a loss and seven quarterback hits.
