ABC's Dancing With the Stars might be saying goodbye to another longtime pro heading into its 20th season in March.

Karina Smirnoff may be the latest pro to sit out of Dancing With the Stars as it approaches the landmark 20th season, which is the 10th anniversary of the show. The pro appeared at the Dancing With the Stars Live! Tour in Denver this past weekend and apparently suggested that she wouldn't return.

A site called Terri Clark's Litcetera (discovered via Wetpaint) reported on the tour stop and revealed that Smirnoff said there would be a "major overhaul" for season 20 this spring. The report said that Smirnoff then "intimated" that she herself was not returning for season 20.

There is no word on if Smirnoff intends to return to the show for season 21 or later.

If Smirnoff sits out of season 20 this would be the third significant pro to not compete in the upcoming season. Cheryl Burke already announced that she was leaving the show to pursue other career opportunities while Derek Hough announced recently that he would be the male lead in the New York Spring Spectacular, so he is sitting out of this season.

With Burke, Hough and now probably Smirnoff out, Dancing With the Stars might indeed be undergoing a large "overhaul." However, it could provide the opportunity for the show to introduce some new star dancers to the mix.

Dancing With the Stars is slated to return for season 20 on Monday, March 16 at 8 p.m. ET/PT on ABC.
