PITTSBURGH -- Steelers quarterback Kenny Pickett exited the first half against the Jaguars on Sunday with a rib injury, and he was ruled out for the rest of the game. Mitch Trubisky finished the game for Pittsburgh, who made a brief rally but ultimately was on the short end of a 20-10 final score. 

Despite the injury, Pickett said that he will play on Thursday night against the visiting Tennessee Titans, who will start rookie quarterback Will Levis following his four-touchdown performance against the Atlanta Falcons

"I'm playing, for sure," Pickett said, via ESPN

The injury occurred when Pickett was hit by Jaguars defensive lineman Adam Gotsis on a first-down pass attempt with 17 seconds left until halftime. Pickett stayed on the ground for several moments before leaving the field under his own power.

After a slow start, Pickett finished the half with 73 yards on 10 of 16 passing. He made several key plays on Pittsburgh's 12-play, 93-yard scoring drive that cut their deficit to three points late in the first half.

The Steelers do have an experienced backup in Trubisky, a former Pro Bowler with the Bears who has made 57 starts during his seven-year NFL career. He went 2-3 as the Steelers' starting quarterback last season that included a road win over the Panthers in Week 15. 

But Trubisky was unable to lead the Steelers back on Sunday after trailing 9-3 at halftime. While he did connect with George Pickens for the team's lone touchdown, Trubisky's two interceptions played a role in Pittsburgh's third loss of the season. 

"I've got to be smarter," Trubisky said afterward. "I'm out there trying to win the game. ... I wanted to push the ball down the field, and that was the wrong thing to do (on his second interception). Got to learn from it."

Thursday night's game is a big one for the 4-3 Steelers, who need a win in order to keep pace with the Bengals, Browns and Ravens in the AFC North division race. Pittsburgh also needs a win to keep pace with the rest of the field in the AFC playoff standings.
