This is not the week for Gleb Savchenko to get sick.
“He has the flu and has to rest up this weekend so he can hopefully dance on Monday,” a source tells PEOPLE of the Dancing with the Stars pro.
Savchenko and his season 23 partner Jana Kramer are just two nights away from possibly winning the Mirrorball Trophy but the pro is having to reschedule rehearsals this weekend so he can rest, says the source.
Kramer and Savchenko are slated to face-off against Laurie Hernandez and Val Chmerkovskiy, Calvin Johnson and Lindsay Arnold and James Hinchcliffe and Sharna Burgess for two dances on Monday night. And if they are not eliminated Monday, they will have just 24 hours to learn a new dance for the season finale on Tuesday.

“Getting to the final week makes me already feel like a winner,” Kramer — who posted an Instagram Saturday of Savchenko wearing a mask in rehearsal — told reporters after last Monday’s live show. “But don’t get me wrong, I still want that Mirrorball!”
The source says Savchenko can’t imagine not performing Monday, but it will have to be a game-day decision. The pro dancer almost had to sit out of a live performance earlier in November after suffering a knee injury.
Dancing with the Stars finale week kicks off Monday at 8 p.m. ET on ABC.
