Trubisky injures left shoulder, Allen suffers concussion

Updated Mar. 4, 2020 4:10 p.m. ET

Only four weeks into the regular season and it's already been a rough time health-wise for several NFL starting quarterbacks.

The Steelers' Ben Roethlisberger is out for the season with an elbow injury. The Saints' Drew Brees is out several weeks with a thumb injury. The Panthers' Cam Newton has a foot injury, the Jets' Sam Darnold has been out with mono and Jacksonville's Nick Foles will miss several weeks with a broken collarbone.

And two more got hurt Sunday.

The Bears' Mitchell Trubisky left the game against Minnesota because of a left shoulder injury. A scrambling Trubisky was hurt on the opening possession. Danielle Hunter dragged him down and the quarterback's arm got pinned awkwardly under his body as the ball popped out. Minnesota recovered the fumble, but a holding penalty against Anthony Harris negated the play.

Bills quarterback Josh Allen was placed in the NFL's concussion protocol after taking a helmet-to-helmet hit by Patriots defensive back Jonathan Jones in the opening minute of the fourth quarter of a 16-10 loss to New England.

The hit occurred when Allen scrambled out of the pocket and burst through a hole up the middle while facing third-and-8 at the New England 45. He gained 7 yards before Jones closed in on him, lowered his helmet and struck the quarterback in the crown of his helmet. Jones was flagged for a personal foul for unnecessary roughness.

Allen lay on the field for several minutes before hopping up on his own. He was briefly evaluated on the sideline before being escorted up the tunnel. Allen was spotted in the locker room chatting with teammates following the game.
