Michigan State will play its next two games without Foster Loyer on the floor.

Head coach Tom Izzo told reporters on Thursday that Loyer will sit out for a week to recover from a shoulder injury that limited him in the Spartans’ 75-65 loss to Purdue. He will miss at least two games, and there’s potential that the guard could miss more time, though no decision has been made.

“We’re gonna give him a week anyway. It’s kind of what he decided, the trainer and myself,” Izzo said, per the Detroit Free Press. “He does not want to have surgery during the year. He wants to finish it off. ..There’s some guys that just get surgery, and he doesn’t want to leave his teammates, he doesn’t want to feel like he’s bailing out on a season, so he’s not going to do that.”

Izzo said that Loyer initially suffered the injury in Michigan State’s Feb. 6 game against Nebraska and aggravated it against Penn State just a few days later. The guard played just two minutes for the Spartans against Purdue on Tuesday.

Michigan State’s next two games are against Indiana and No. 5 Illinois. Loyer is averaging 4.2 points, 2.3 assists and 1.6 rebounds per game for the Spartans this season.
