I listened to his audio interview on the FFT website
and he talks again about his injury. He says it was not really a problem tonight, but it's been bothering him for a while now and hampering him in training, so it might be a factor too. (I wonder why he played in DC then - just because they wanted to take their revenge for last year?!)
He says he'll see now with Montalvan what he needs to do to get rid of this injury because for the rest, he really is eager to play, the motivation is not the problem right now.
