Coach Matt Eberflus confirmed Monday that Fields suffered a dislocated right thumb in Sunday's loss to the Vikings and is "doubtful" for Week 7 against the Raiders, Kevin Fishbain of The Athletic reports.

EDGE Analysis

Eberflus noted that it's all going to come down to "grip strength" when discussing Fields' timetable. Undrafted rookie Tyson Bagent won the Bears' QB2 job after a surprising preseason and came in in relief of Fields on Sunday. Bagent lost a fumble that was returned for a touchdown on his very first snap and finished 10-for-14 passing for 83 yards, no touchdowns and one interception. Chicago also could opt to start veteran Nathan Peterman versus Las Vegas.
