Steelers QB Kenny Pickett out vs. Buccaneers with concussion, replaced by Mitch Trubisky

Pittsburgh Steelers quarterback Kenny Pickett left their game against the Tampa Bay Buccaneers early on Sunday after taking a shot in the third quarter.

Pickett had just thrown the ball away when Buccaneers linebacker Devin White drilled him in the pocket, which sent Pickett to the ground hard. As he went down, his head whipped back and hit the turf.

Pickett was slow to get up and went right to the medical tent before heading to the locker room.

The Steelers then replaced him with Mitch Trubisky, who started the season in Pittsburgh. The team said Pickett, 24, was being evaluated for a concussion, and later ruled him out.

Pickett finished his day 11-of-18 for 67 yards. He threw one touchdown early, finding Najee Harris for a six-yard score in the first quarter, which marked the first of his career.

Pickett, the Steelers' first-round draft pick in April, replaced Trubisky officially before last week's blowout loss to the Buffalo Bills. Trubisky went 1-4 as a starter in Pittsburgh.

The Steelers led 13-12 when Pickett went down.
