Strikeforce Heavyweight Grand Prix champion Daniel Cormier is slatd to make his final appearance for the promotion against ex-UFC heavyweight champion Frank Mir.

However, no official date or location has been announced for the card, leaving Cormier to ponder when he’ll return to action.

“They still haven’t given me a date, but I think they are getting pretty close,” said Cormier, during a recent appearance on BJ Penn Radio. “It’s not like we have that much time anymore. I would expect that we would know something pretty soon.”

Cormier cited a rapidly-filling up December month with several UFC events, adding, “It’s kind of odd that we don’t know when and where we are fighting considering they already have a full card booked and a venue for their UFC on Fox card in December.”

“DC” is expected to transition into the UFC following the bout with Mir.
