The absence of several familiar professionals is the result of a cast that will feature 11 celebrity participants, according to E! News, which is fewer than the 16 couples that competed on last fall's ninth season -- the most ever for the show -- or the 13 that participated in the show's prior two editions.
"It wasn't easy," a source told E! News about which professional partners would be returning. "Producers cut people based on the celebrities and who they'd be a good match with."
