Bears' Justin Fields has dislocated thumb; doubtful vs. Raiders - ESPN

CHICAGO — Bears quarterback Justin Fields has a dislocated right thumb and is doubtful to play against the Las Vegas Raiders in Week 7, coach Matt Eberflus said Monday.

Fields suffered the injury in the third quarter of the Bears' 19-13 loss to the Minnesota Vikings on Sunday. X-rays were negative, but he had an MRI on Monday.

Eberflus said the Bears anticipate knowing whether Fields will need surgery on his thumb in a few days. The Bears coach said he did not get any feedback on what the MRI revealed and reiterated that Fields' ability to grip the ball will be paramount in determining next steps.

Fields was working with trainers at Halas Hall on Monday, and Eberflus said he just wants to «give it time» for the swelling to go down.

«It doesn't look like it's a negative thing,» Eberflus said when asked if Fields had any torn ligaments, «but we'll see where it is.»

Fields injured the thumb after landing on his right arm while being sacked by Vikings defensive end Danielle Hunter on Chicago's first drive of the third quarter. As Fields was falling to the ground, he tried to flip the ball in the direction of running back Darrynton Evans.

After a visit to the injury tent, Fields walked back to the locker room with a towel over his right hand. He was initially listed as questionable to return and ruled out shortly thereafter.

Rookie QB Tyson Bagent made his NFL debut in place of Fields on Sunday and completed 10 of 14 passes for 83 yards and interception an had a 1-yard QB sneak to cap Chicago's only touchdown drive.
