He gets a day's rest so I guess he will be ok for the next round.
He insisted to play today to get a day off tomorrow.
All credit to Berrer for finding his way into the match after a nervous performance in the first set. He had over 80% on 1st serve in the second set whilst Roger seemed to be anywhere but not on the court until being down 0:4.
Too many UEs from Roger and he clearly wasn't convinced with his performance today.
