One fan favorite Dancing with the Stars pro won’t be hitting the dance floor this week.
Cameras were rolling when the injury took place, and Chmerkovskiy, 37, was mid-spin with his partner Heather Morris when he suddenly cried out in pain and clutched at his leg.
“It’s my calf muscle,” he said. “It just felt like something hit it.”

Troupe dancer Alan Bersten will be taking Chmerkovskiy’s place for the time being.
Dancing with the Stars airs Mondays (8 p.m. ET) on ABC.
