Justin Fields suffered a dislocated thumb on his right hand on Sunday during the Chicago Bears’ 19-13 loss to the Minnesota Vikings, according to NFL insider Ian Rapoport.

Fields is set to have an MRI on Monday to determine any additional damage.

The former Ohio State quarterback sustained the injury when he was sacked on third-and-7 by Vikings defensive lineman Danielle Hunter during the first drive of the third quarter. Fields fell awkwardly on his right arm, trying to break his fall as he attempted to flip the ball within the reach of running back Darrynton Evans.

Fields headed to the injury tent and walked to the locker room with a towel over his right hand.

Head coach Matt Eberflus told reporters after the game that Fields wanted to come back into the game, but was unable to grip the ball and throw it.

“His demeanor is great,” Eberflus said. “He goes, ‘Coach, we’ll see where it is tomorrow.’ He was positive and he was upbeat.”

Fields finished his day 6-of-10 passing for 58 yards and an interception. He also carried the ball 8 times for 46 yards.

Rookie quarterback Tyson Bagent out of Shepherd entered the game in Fields’ place, finishing 10-of-14 for 83 yards and an interception. Fields’ status ahead of the upcoming game against the Las Vegas Raiders next Sunday will be something to keep an eye on as the situation develops.
