On a day in which the Bears learned that wide receiver Alshon Jeffery was suspended four games, the team also reportedly found out it will be without offensive lineman Kyle Long for the rest of the season.
Ian Rapoport of the NFL Network reported that Long's MRI came back with the bad news.
Long was carted off the field and returned in the second half with a wrap around his ankle due to the injury. His injury was part of a number of key injuries the Bears suffered on Sunday, including fellow offensive lineman Bobby Massie and running back Jordan Howard.
The 27-year-old missed just one game in his first three seasons in the NFL, totaling 47 starts. This season, Long also missed the Week 8 game against the Vikings.
