Morgan made a crude remark about the key Republican’s looks during an appearance Thursday on “Inside the NBA."
During a pre-game chat ahead of the Miami Heat-New York Knicks clash, co-host Charles Barkley asked the actor, “Sarah Palin’s good looking, isn’t she?”
Morgan replied, "Let me tell you something about Sarah Palin, she's good masturbation material. The glasses and all of that... She is great masturbation material."
TNT issued the apology within minutes amid outraged phone calls and emails about Morgan's comments, USA Today reported.
"It's unfortunate Morgan showed a lack of judgment on our air with his inappropriate comments," said Turner spokesman Jeff Pomeroy in a statement.
