Minnesota’s Karl-Anthony Towns will have surgery next week to address a meniscus tear in his left knee. The team announced the injury Thursday night, saying Towns will miss at least four weeks. That means the All-Star will be sidelined for at least 13 more games. That’s the majority of Minnesota’s remaining regular-season schedule. The Wolves sit atop the Western Conference. Towns didn’t play in the Wolves’ win at Indiana on Thursday night. The team revealed after the game that an MRI exam, performed Wednesday, showed the meniscus tear.
