Jacksonville gave up its fifth-round pick in the 2020 draft for Dobbs, who was in his third season with the Steelers. He was a fourth-round selection out of Tennessee in 2017.
Dobbs, who has played in five career games, will back up rookie Gardner Minshew. Minshew completed 22 of 25 passes for 275 yards, with two touchdowns and an interception, in his NFL debut Sunday.
Minshew replaced Foles in the first quarter and completed 88% of his passes, becoming the most accurate single-game passer in Jaguars history (minimum 25 attempts). His completion percentage also was the highest for any player with at least 15 pass attempts making his NFL debut.
Foles suffered a broken left clavicle on Jacksonville’s 10th offensive play of the season. He was hit and landed on the shoulder while throwing a 35-yard touchdown pass to DJ Chark.
The Jaguars placed Foles on injured reserve Monday. If he’s designated to return, as the team expects, Foles would be eligible to return to practice in late October and would be eligible to play in Week 11 at Indianapolis.
