CHICAGO -- Bears quarterback Mitchell Trubisky has been ruled out of the remainder of Sunday's home game against the Vikings with a left shoulder injury.
The Vikings knocked Trubisky out of the game on the Bears' sixth offensive play of the afternoon when Minnesota defensive end Danielle Hunter sacked the 25-year old quarterback for a 10-yard loss.
On the play, Trubisky's body twisted and his left shoulder hit the ground violently as Hunter pulled him down, causing the quarterback to fumble the ball. Minnesota's Everson Griffen scooped up the fumble, though a defensive holding penalty on Vikings safety Anthony Harris gave the ball back to Chicago.
Trubisky immediately went to the blue injury tent before being escorted back to the locker room for further medical attention.
Veteran backup Chase Daniel replaced Trubisky and tossed a first-quarter touchdown pass to Bears running back Tarik Cohen.
The second overall pick of the 2017 draft, Trubisky started all 12 games as a rookie after taking over for ineffective Mike Glennon in Week 5 but missed two games last year because of a right shoulder injury.
Trubisky finished last season with respectable numbers in head coach Matt Nagy's system, passing for 3,223 yards, 24 touchdowns and 12 interceptions (95.4 quarterback rating) as Chicago went 12-4 and won its first NFC North title since 2010.
But Trubisky struggled to begin the 2019 season.
After lackluster performances versus Green Bay and Denver, Trubisky got back on track in the Bears' victory over the Redskins last Monday night, throwing for a season-high 231 yards, three touchdowns and one interception. Trubisky had completed 2 of 3 passes for nine yards at the time of his injury on Sunday.
The Bears signed Daniel, who played under Nagy in Kansas City, to a two-year deal prior to the 2018 season that included $7 million in guarantees. Daniel will earn $6 million in 2019.
Daniel, 32, appeared in five games with two starts for the Bears last season.
