Roy Nelson has been firing off several messages via Twitter discussing who he might bring on as a coach for The Ultimate Fighter.

Nelson, who will compete opposite Shane Carwin on the show beginning later this year, posted a complete list of athletes and others on his own website that were allowed and not-allowed by the UFC.

Carwin recently announced his staff, which includes Strikeforce welterweight champion Nate Marquardt.

Welterweights will comprise the season of TUF, which begins shooting next month and airs in September on FX. The two heavyweight coaches are expected to face each other later in the year.
