The injury picked up by Tomas Rosicky at Salzburg on Wednesday is thought to be minor.
The Czech midfielder limped off just after the half-hour at the Bulls Arena, seemingly in some discomfort.

However afterwards Arsène Wenger played down any fears.
"We don't think it is serious," said the manager. "He had a tight hamstring and we did not want to take a gamble."
