It looks like Dancing with the Stars
will be down one competitor when it airs Monday night.
, 31, has injured
herself and is out of the competition, her castmate Brooke Burke confirms.
"It's such a sad situation," Burke said Monday during a radio interview on 104.3 MY fm's Valentine in the Morning. "She did hurt her Achilles tendon. I don’t know if she tore it or she ruptured it. It happened this week. She's out of the competition, I mean, just like that."
ABC confirmed the Olympian's injury on Saturday, saying at the time she was "resting comfortably at home." The network will make an official announcement regarding May-Treanor's Dancing
future on tonight's show.
But according to Burke, May-Treanor may undergo surgery for her injury.
"Forget about the competition," Burke said. "This is her jumping mechanism, so we're all really concerned for her. She may be having surgery this week. We don't know yet. But it's such a bummer."
"You take somebody like her who's a supreme athlete," Burke said, continuing, "and you think she's one of the strongest in the bunch. We're just doing stuff we've never done before and pushing our bodies to the limits. And just like that it's over for her." --Brian Orloff
