The past Mirror Ball champ is partnered with "Glee" star Heather Morris for this season and she survived this past week's cut, dancing with pro stand-in Alan Bersten.
"Gettin' un-broken," he wrote early Thursday morning, with an IV in hand.
Chmerkovskiy's fiancee Peta Murgatroyd previously told "Access Hollywood" that he is getting surgery for tears in his calf muscle.
"It's gonna take a couple of weeks at least to get better," she told the outlet. "He's having a surgery done," but she added that he's a fighter and will be back as soon as he can.
His "un-broken" post wasn't the only one this week for his fans.
"Thank you all for so much love and support! And for having @heatherrelizabethh back with all your votes I'm also very excited about her and @alanbersten Tango next week," the injured dancer wrote Tuesday on Instagram. "Please rest assured that I'm taking this thing very seriously and, although I don't have a concrete return date, I'll give it my all!"
Chmerkovskiy followed up his sincere post with a funny video on Tuesday.
"Ah'll bee buck!" he captioned a video showing him using some sort of walking device to keep his calf rested and off the ground.
On Monday's show, comedian Chris Kattan was sent home, while Morris scored a 30 out of 40, near the top of the leaderboard. Normani Kordei and Maksim's brother, Val Chmerkovskiy, and Rashad Jennings and Emma Slater, both scored 32 to lead the way this week.
