Nate Myles has been ruled out of the Gold Coast side for Saturday's NRL clash against the Warriors at Skilled Park.
The Wally Lewis medal winner for Queensland's player of the series in their 2-1 State of Origin victory, Myles suffered a sternum injury in the Maroons' 21-20 win on Wednesday night.
"Nate won't play. He copped a pretty bad knock on his sternum," Titans coach John Cartwright said in a statement on Friday.
"It's not a long-term injury but it's going to be with him for the rest of the year and it's a bit tender at the moment.
"For Nate, it's just too much on his body. As you saw the other night, he leaves nothing on the field and he'd do the same to play on Saturday night but the long-term risk is not worth it."
