He pulled up short in the second set and there seemed to be a problem with his right hip.
He had extensive off-court treatment and continued on for a set...but it was clear that he couldn't move well.
I hope it is nothing too serious but I'd say he could be a doubt for Wimbledon.
Recover quickly Greg
...and I'd think the Davis Cup question will have been answered today...I'll be surprised if he commits as he will need to work extra hard to recover his huge points haul after Wimby.
