The Western Conference-leading Minnesota Timberwolves will be without star forward Karl-Anthony Towns for at least four weeks after he undergoes surgery to repair a meniscus tear in his left knee, the team announced Thursday night.

With Towns expected to miss at least four weeks, he would, at minimum, be sidelined for at least 13 more games – the majority of the Timberwolves’ remaining schedule.

The team revealed after Thursday’s 113-111 win over Indiana that an MRI exam, performed Wednesday, showed the tear.

He will undergo surgery early next week.

“It’s not a plug-in one person to fill Karl’s role kind of situation,” Wolves coach Chris Finch said. “What I love about our team is that we have a multitude of options. We can go a lot of different ways based on matchups on any given night. We’ve started different guys through the season anyway.”

An All-Star for the fourth time, Towns is averaging 22.1 points and 8.4 rebounds per game while sinking a career-best 42.3 percent from 3-point range. He is one five players in the league averaging at least 20 points, shooting 50 percent from the field and 40 percent on 3-pointers.
