The Dancing With the Stars family is definitely missing Maksim Chmerkovskiy.
The popular 37-year-old pro dancer missed week two of the show due to a calf injury he suffered during rehearsals with his partner, Glee actress Heather Morris. ET caught up with the DWTS cast backstage on Monday night, where they gave updates on his injury.
"I don't know what happened," Chmerkovskiy's fiancee, Peta Murgatroyd, told ET's Cameron Mathison. "It was a freak accident. His calf just popped, it was very weird."
"You have to stretch, you have to warm up, you have to make sure your body is ready to go," she added about how she's working to prevent her own injury. "You have to feed it vitamins, you have to drink a lot of water. You have to take care of yourself. That's the bottom line."
Chmerkovskiy's brother, Val, said that the new dad is definitely on the mend, and is undergoing therapy.
"He's good, he's the better bro," he joked. "He's going to be alright."
"He's just going to get therapy and hopefully recuperate quickly, and hopefully the Chmerkovskiy gene is going to kick in and he's going to recover quick," he continued.
Sharna Burgess also revealed to ET that Chmerkovskiy is going to the same doctor that she worked with when she got hurt last season.
"He is Dr. Williams, he's in Ohio," she shared. "He is absolutely incredible. He got me back in two weeks and hopefully he will do the same for Maks."
Meanwhile, troupe dancer Alan Bersten -- who stepped in just two days prior to dance with Morris -- said that he knows Chmerkovskiy will make a quick recovery.
"I don't know specifically what he's doing, but I know it's going to be a speedy recovery and he is a very humble man," he noted. "He's really just like, 'Pretend like nothing's going on,' and constantly like, 'Just sit down, like, just take the help, you need it,' so I know he is going to be quick to recover."
Despite Chmerkovskiy's unfortunate sidelining, Morris still nailed her jive routine on Monday's show, and her partner couldn't be prouder.
"I'm so proud of @heatherrelizabethh for getting it done in an amazing fashion!" he Instagrammed on Monday, also thanking Bersten. "I'm sorry I couldn't be next to you, but I promise to work harder than ever and get my a** back to the ballroom as soon as humanly possible!"
"And finally, to all our fans... I've said in the beginning of the season that I was back because of how supportive you've always been to me, and I promise that this isn't the last you've seen of me," he added. "I will make every effort to make you proud yet... In the mean time PLEASE VOTE FOR #teamMaksimumHeat!!!"
