Fly-half taken from the field in a neck-brace in warm-up game against Rebels.
Queensland Reds fly-half Quade Cooper is in doubt for the opening game of the Super 15 season after being stretchered off in a neck brace during a friendly against the Melbourne Rebels.
The Wallaby vice-captain suffered a jolting hit from behind in the final minute of the match on Friday evening, with a dozen medics and officials attending him.
Reds coach Richard Graham said he would undergo scans but dismissed any concerns about concussion.
“He’s all right,” said Graham. “I had a chat to him and he’s in good spirits but it (scans) is one of those things we have to do.
“He’s come off, he’s alert, he’s talking, he’s disappointed.”
The Rebels, under new coach Tony McGahan, won the match in Brisbane 18-13.
The Super 15 season kicks off later Saturday with two South African derbies, involving the Cheetahs and Lions in Bloemfontein and the Sharks and Bulls in Durban.
Australian and New Zealand teams debut next weekend, with the Reds due to face the ACT Brumbies in Canberra.
