Falcons QB Marcus Mariota to undergo procedure on knee play What can Falcons expect from Desmond Ridder as the starting QB? (1:27) Dan Orlovsky details what the Falcons will get from Desmond Ridder after the team named him the starting quarterback. (1:27) 12:35 PM ET Michael RothsteinESPN Staff Writer Close Previously covered University of Michigan for ESPN.com and AnnArbor.com Also covered Notre Dame for Fort Wayne Journal Gazette FLOWERY BRANCH, Ga. -- Atlanta Falcons backup quarterback Marcus Mariota will be placed on injured reserve Wednesday and is expected to have a procedure on his knee scheduled for next week, according to Falcons head coach Arthur Smith. The Falcons had benched Mariota in favor of rookie quarterback Desmond Ridder during the team's off week last week. Smith declined to say when they learned of Mariota's knee injury, which Smith said Monday was chronic and not part of the decision to move from Mariota to Ridder, just that he is going to be having a procedure next week. Mariota left the team in search of doctor's opinions before Saturday. Editor's Picks Falcons' move to QB Ridder 'performance-based' 2d Michael Rothstein 1 Related "Things come up. Those are the things that happen in pro football," Smith said. "A guy has an issue, goes to see a doctor. That's what happens." Falcons quarterbacks coach Charles London declined to talk about Mariota's injury, just that "we wish Marcus the best." Mariota was not listed on the Atlanta injury report at any point this season. Mariota completed 184 of 300 passes for 2,219 yards, 15 touchdowns and nine interceptions. Atlanta lost four of its last five games with Mariota as quarterback. Smith also didn't want to discuss whether or not Mariota would have been beneficial on the sidelines for the rest of the season, too. Logan Woodside , signed Saturday off Tennessee's practice squad, will serve as Ridder's backup. Woodside, the experienced quarterback in the room, is 1 of 3 for seven yards in his career -- those reps coming in 2020 with Tennessee under Smith, who was the Titans' offensive coordinator at the time. Woodside also has 13 carries for four yards in his career between 2020 and 2021. Smith also said starting defensive lineman Ta'Quon Graham, who suffered a knee injury last month, will not be expected back this season.
