Trouble continues to plague "Lethal Weapon."

Star Damon Wayans announced in a video interview that he plans to leave the Fox cop show at the end of the year, halfway through the third season. The move comes just a few months after his former co-star, Clayne Crawford, was fired for abusive behavior on set.

Wayans cited his age as a primary reason for his exit.

“I’m going to be quitting the show in December after we finish the initial 13 [episodes],” he told the Electronic Urban Report. "So I really don’t know what they’re planning, but that’s what I’m planning. I’m a 58-year-old diabetic and I’m working 16-hour days.”

He continued, referring to his character,  "Like Murtaugh said, I’m too old for this.”

Around the time of Crawford's departure, reports emerged that the two stars often butted heads. One actor described the situation as, "Damon is used to sitcom work and Clayne is used to cable drama. Damon likes sitcom hours, while Clayne wanted the show to be Emmy material. It was oil and water."

In May, Seann William Scott was brought on to replace Crawford as Murtaugh's new partner for Season 3. But now, it seems neither of the original "Lethal Weapon" characters will be around.

As for what Wayans wants to do next, he said, "I’m going to return to the stage and try to find my smile again."
