Anthony Pettis just can't catch a break.

After missing out on two title shots over the last two years, "Showtime" told MMAFighting.com on Tuesday that he recently missed out on being a coach on "The Ultimate Fighter."

"[I'm] still recovering from shoulder surgery," he said, "and it's taking longer than expected. I was hoping to get 'The Ultimate Fighter' gig because I was told it was me and [Donald] Cerrone coaching, and now it's not happening. I'm just frustrated with everything, man."

Pettis underwent shoulder surgery earlier this year following his win over Joe Lauzon in February. Over the summer, he said he was hoping to settle his recent beef with Cerrone in November or December but those plans have since changed.

"I'm hoping to return in January," he said.

The UFC announced on Tuesday that Jon Jones and Chael Sonnen will coach next season's The Ultimate Fighter.
