Odds are, it'll be Kevin Glenn taking the snaps tonight for the Hamilton Tiger-Cats.
The veteran quarterback has been taking the lion's share of reps in practice this week with starter Quinton Porter nursing a sore knee.
"That's up to the coach, I don't make those decisions, I just go out there and prepare as though I'm going to start," said Glenn.
"We'll see when game time comes. When you're a quarterback, whether you're No. 1, 2 or 3, you have to prepare as though you're going to play. That's how I've always approached the game and that's how I'm going to continue to approach the game."
Porter was under centre the last time the two teams met three weeks ago.
The second-year quarterback, scored a touchdown in the final minute, which gave the Tiger-Cats a 28-21 win.
The following week, Porter was pulled in favour of Glenn in a loss to the Saskatchewan Roughriders.
"The decision really comes down to one simple thing," said Tiger-Cats head coach Marcel Bellefeuille.
"Quinton has a little bit of a sore knee, there is nothing structural to it, it's healthy, we just have to feel confident that he'll be able to do everything athletically that he needs to do, that he'll be able to run and do those things at 100%."
Glenn threw for 183 yards and a touchdown in the 33-23 loss to Saskatchewan.
He has thrown three touchdown passes and an interception in a back-up role for the Tiger-Cats this season.
"This year hasn't been any different for me, you have to come out and be a team player," Glenn said. "Whatever capacity you contribute to, you have to do it at 110% and that's the way I've always approached it.
"I've been in this league a long time to where I've been a backup before. It's nothing different, you prepare as though you're going to play because you never know when the opportunity is going to come. You have to take advantage of when you get it."
Against the Roughriders, Glenn was able to get the Tiger-Cats back in the contest after falling behind 23-0 at half time. However, the comeback fell short.
"It was more a learning experience for the team, we have a young team," Glenn said. "It's something we can learn from, where we have to come out and play the first 30 minutes and not sit back and wait. The biggest thing with that game was execution. We didn't execute in the first half and we did in the second half and it showed."
