Kramer posted a photo on Instagram Saturday, showing Savchenko standing next to her, wearing a surgical mask. "One of us has the flu...well maybe two of us," Kramer wrote, adding, "Excuse me while I go vitamin C overdose."

A few hours later, Kramer posted another Instagram photo, this time with her wearing the mask and joined by DWTS pro Alan Bersten, with the caption: "I'm being quarantined with @alanbersten. Please feel better @glebsavchenkoofficial #flu."

Savchenko was also sidelined briefly earlier this month after he suffered from a knee injury.

Kramer will face off tonight against Indy Car driver James Hinchcliffe, Olympic gymnast Laurie Hernandez, and former NFL player Calvin Johnson Jr. for the "Dancing with the Stars" mirror ball trophy at 8 p.m. ET on ABC.
