Give it a rest. The guy ran big 9.71pb on a groin that was clearly giving him trouble and I can also tell you he was in Germany for therapy for several months this winter.
He’s tough as nails and is anything but a quitter as anyone in the know could tell you.
As I pointed out earlier on another thread, he should have pulled out of the 200m in London as that clearly aggrivated it. (In that case, he was too tough for his own good!)
