Paris - Toulouse's New Zealand flyhalf Luke McAlister is expected to be out for up to four months after rupturing a tendon in his biceps.
The 30-year-old announced the news on his Twitter account on Saturday.
"Gutted to be told I'm out for 3/4 months torn bicep tendon staying positive & will work hard to come back better thanks for all your concern," he wrote.
McAlister was forced off five minutes before half-time of Toulouse's 17-16 Heineken Cup win at Saracens on Friday night.
He had suffered a miserable night, missing three kicks at goal and skewing two clearing kicks almost directly into touch.
It's not all bad news for Toulouse, though, as former France flyhalf Lionel Beauxis is set to make his comeback from an ankle injury.
