(CBS) The Bears suffered a significant loss in Sunday’s preseason game as receiver Cam Meredith was carted off with his left leg in air cast. Coach John Fox said after the game the team suspects he suffered a torn ACL. 

Meredith had his left leg buckle in an unnatural position while being tackled on a reception in the first quarter against the Titans. He immediately grabbed his left knee, and teammates motioned for medical assistance. The cart came out and took Meredith away, with the Bears quickly ruling him out for the game.

Meredith emerged as the Bears’ top receiver in 2016, posting 66 catches for 888 yards and four touchdowns. An undrafted free agent in 2015, he emerged as a starter and took advantage of an opportunity after Kevin White suffered a season-ending injury last season.

After losing Alshon Jeffery to Philadelphia in free agency, the Bears were counting on Meredith to fill a role at receiver. 

Meredith will undergo an MRI on Monday.
