SPOKANE, Wash. — Second-ranked Gonzaga is battling injuries and will be shorthanded heading into Saturday’s game against Pacific.

Freshman Anton Watson is out for the rest of the season after it was decided last week he would have shoulder surgery. Leading scorer and rebounder Filip Petrusev had to leave last Saturday’s game against BYU early in the second half because of a high ankle sprain. It’s unclear when he will return.

That leaves a very thin bench for the Bulldogs.

“It’s part of the game,” coach Mark Few said after the BYU game. “We’ve got to keep playing.”

Petrusev, who averages 16.7 points and 7.9 rebounds per game, is a 6-foot-11 sophomore forward from Serbia.

Watson averaged nearly five points and three rebounds in about 15 minutes per game.

Earlier this season, the Zags lost freshman Oumar Ballo to an academic redshirt. Freshman Brock Ravet, who was expected to contribute, left the team for personal reasons.

That leaves a rotation of six players: Corey Kispert, Killian Tillie, Joel Ayayi, Admon Gilder, Ryan Woolridge and Drew Timme.

Gonzaga (20-1, 6-0 West Coast) has 10 remaining regular season games.

The injuries may force adjustments.

“You’ve got to be smart on the risks you take, especially on defense ... we just can’t afford to lose another guy,” Kispert said.
