The Cleveland Browns placed starting defensive tackle Shelby Harris on injured reserve on Thursday because of an elbow issue.

The Browns (3-12) host the Miami Dolphins (7-8) on Sunday before completing their season against the Baltimore Ravens in Week 18.

Quarterback Dorian Thompson-Robinson, who started last week’s 24-6 loss to the Cincinnati Bengals and aggravated his calf injury, is expected to start against the Dolphins, offensive coordinator Ken Dorsey said Thursday.

“As of right now, I would say Dorian’s healthy,” Dorsey said. “He’s going to be our starter for this week and we’re moving forward with that mindset.”

Thompson-Robinson, 25, was 20-of-34 passing for 157 yards and two interceptions. He replaced starter Jameis Winston (shoulder), with Bailey Zappe serving as his backup.

Cleveland selected Thompson-Robinson in the fifth round of the 2023 NFL Draft. He is 1-3 as a starter, with career totals of 95-of-180 passing for 697 yards, one touchdown and nine interceptions in 13 games.

Harris, who was injured during the 21-7 loss to Kansas City on Dec. 15, had started 13 of 14 games he played this season and totaled 37 tackles, 1.5 sacks, five tackles for loss and one forced fumble.

The Oakland Raiders selected Harris in the seventh round of the 2014 draft. Harris, 33, has 326 career tackles, 27.5 sacks, 51 tackles for loss, 60 quarterback hits, one interception and five forced fumbles in parts of 10 seasons with the Raiders (2014-15), Denver Broncos (2017-21), Seattle Seahawks (2022) and Browns (2023-present).

The Browns signed wide receiver and return man James Proche II from the practice squad to the active roster on Thursday, and signed defensive tackle Michael Dwumfour to the practice squad.

Proche, 28, has three receptions on three targets for 21 yards in seven games this season. He also has returned 18 punts for 163 yards for a 9.1 average. A sixth-round draft pick by Baltimore in 2020, Proche has 28 career receptions for 299 yards in 60 games (one start) for the Ravens (2020-22) and Browns (2023-present).

Dwumfour, 26, was in training camp and spent time on the Browns’ practice squad this year. He played in 12 NFL games with the Houston Texans (2021-22) and San Francisco 49ers (2022) and has 13 total tackles.
