Sunday's game between the Hamilton Tiger-Cats and Winnipeg Blue Bombers took a turn for the worse after both starting quarterbacks exited with injuries.
Tiger-Cats QB Bo Levi Mitchell was taken off the field in an ambulance after taking a sack from Jake Ceresna, where his foot appeared to get caught under the Blue Bombers lineman.
The 14-year-old CFL veteran gave a thumbs-up to the crowd as he was lifted from the stretcher into the ambulance.
Hamilton later ruled Mitchell out with a lower-body injury.
Mitchell, who had been off to a strong start in 2026, had completed 18-of-29 passes on Sunday for 228 yards and one touchdown. The 36-year-old entered the matchup against Winnipeg with 879 yards passing, eight touchdowns and one interception through his first three games — two of which were Tiger-Cats victories.
Tre Ford entered in Mitchell's place under centre.
"If he's out for a while, I'll feel for Bo the person," Tiger-Cats Scott Milanovich said. "I told you guys in training camp he's been on a tear.
"It's the best I've ever seen him play and I think he is/was depending on the situation, poised to have just a monster year. Hopefully he'll be back but if he's not then we're going to have to pick up the pieces."
Collaros, meanwhile, was ruled out by the Blue Bombers with an upper-body injury.
The three-time Grey Cup champion appeared to be injured on a sack in the second quarter, when Hamilton defensive back Reggie Stubblefield sacked Collaros up high.
Collaros stayed down on the field on the play before walking off under his own power. He was replaced by Taylor Elgersma on the next Blue Bombers drive.
The 37-year-old Collaros was 5-of-7 in the game for 41 yards, but was intercepted in the first quarter. He entered Sunday with 944 yards, five touchdowns and two interceptions through three games.
While the injuries put a cloud over the game, it did pave way for some history.
Ford and Elgersma became the first U Sports quarterbacks to both attempt a pass in the same CFL game since Frank Cosentino and Russ Jackson in 1969.
"Two premier starting quarterbacks going down in the same game is not good for the league," said Winnipeg head coach Mike O'Shea. "Hopefully both guys make a speedy recovery, I don't know anything about either one right now.
"Bo was on a heater and the league needs that and obviously we believe Zach is the best quarterback in the league. When you lose that, the game ends up probably the lowest-scoring game this season I'd imagine."
The Blue Bombers won the game 14-13, the lowest-scoring game of the season.
