Memo to Chuck Liddell's (Pictures) future opponents: Slip the UFC light heavyweight champion a NyQuil-based mickey and you should have a much better chance of taking the belt.

In Dallas to promote Warner Bros. latest theatric release "300," Liddell appeared on Good Morning Texas Thursday. From the outset Liddell was not lucid, as he slurred his words and had difficulty putting together sentences.

The UFC champ told Sherdog.com via text messaging that he is very ill and had taken "NyQuil too late."

"I couldn't understand a thing [Liddell] was saying," GMT host Gary Cogill said later for a video piece on the WFFA Channel 8 Web site.

"He takes a lot of Nyquil when he's sick," said Liddell's trainer, John Hackleman. "He goes to bed at 4 a.m. and wakes up at noon, so if they got him up in the morning I can see how he'd be like that."

During the interview, Cogill interjected and asked Liddell if he was OK. Later, Coghill said Liddell momentarily fell asleep.

"I've seen him really close to that before," said Hackleman.

During the conversation with Cogill, Liddell was asked when his next bout would be and whom he would like to fight. "The Iceman" answered that he would return to the Octagon in May. Stammering to recall the name of an opponent, he eventually mentioned boxer Tommy Morrison.

Asked about Morrison, Liddell told Sherdog.com that he was "joking" about the Rocky V star several days ago. Forced to retire from professional boxing after testing positive for the HIV virus in 1996, Morrison was in the news recently after tests no longer showed any traces of the virus known to cause AIDS. Morrison boxed in West Virginia Thursday, Feb. 22, winning by knockout.
