This won't be John O'Korn's first start in a Michigan uniform. It won't even be his first extended stretch of playing time.
But considering the stage this week, O'Korn's Michigan moment is about to officially arrive.
Michigan coach Jim Harbaugh told reporters Monday that fourth-year junior quarterback Wilton Speight will be out "multiple weeks" as he continues to recover from a hit he suffered against Purdue two weeks ago.
With that, quarterback O'Korn will start for the Wolverines when they host rival Michigan State on Saturday night in Ann Arbor (7:30 p.m., ABC).
"We have all the confidence in (O'Korn)," senior left tackle Mason Cole said Monday. "John's ready. Wilton, he'll get healthy. Both these guys are so mentally strong and there's not much that can bring them down.
"These guys are mentally strong, great guys. They'll handle this well."
The status for the remainder of Speight's 2017 season appears to at least be in some doubt, which means O'Korn _ for the first time since his transfer to Michigan from Houston _ will be the unquestioned starter under center.
He won't be subbing in briefly to hold someone else's spot. He won't be coming in for garbage time snaps.
His two backups are a redshirt freshman (Brandon Peters) and a true freshman (Dylan McCaffrey). The job is his now.
And while the circumstances may be unfortunate, O'Korn's opportunity has arrived.
"John performed at (an impressive level) at quarterback (at Purdue)," Michigan senior fullback Khalid Hill said. "And that gives you confidence. Hopefully he can do the same thing this week.
"I know he's preparing to have the best game of his life."
O'Korn's day at Purdue two weeks ago was impressive, as he finished 18 of 26 for 270 yards, 1 touchdown and 1 interception in a 28-10 comeback victory over the Boilermakers in West Lafayette, Ind.
That performance was much better than what Michigan saw in his first start, where he went 7 of 16 for 59 yards in the snow during a 20-10 home win over Indiana last November.
Players say they noticed an improved level of play from O'Korn all offseason and they say the fifth-year senior was able to show it two weeks ago at Purdue.
"The transition was really effortless," Cole added. "He came in like he'd been in there all year. We all knew he'd be ready to play if he had to. And he was."
Two weeks ago, O'Korn found plenty of success against a Purdue secondary that now ranks second-to-last in the Big Ten against the pass.
Michigan State, meanwhile, ranks No. 2 in the league with just 152.3 passing yards allowed per game. The Spartans have only surrendered a 200-yard game once this season, last week against Iowa (202).
Still, Michigan is confident its offense can find a way this week _ with a new face.
"John's done a fantastic job ever since he got here," Harbaugh said. "In every role he's been in, he's acquitted himself very well. Including coming off the bench and leading our team to a victory against Purdue. I think that speaks volumes."
Michigan doesn't believe its in an impossible spot here. The Wolverines have lost a starting quarterback, but they do have the benefit of bringing in a backup who has done this before.
O'Korn _ in another life _ was the American Athletic Conference freshman of the year back in 2013. He had a promising start to his college career.
Now we'll find out if he can close it the same way.
"John's prepared to play, he's always been prepared to play," Michigan defensive tackle Maurice Hurst says. "(O'Korn and Speight) have proven to us that either of them could step in at any moment. We believe in (both)."
