"It's a royal wedding, and those don't come around very often," he said, while admitting that the tight turnaround was "not ideal."
He also told the LA Times, "I'll go to the wedding on Friday, and then I'll fly out of London straight to Dallas on Saturday morning. I'll arrive before the [Galaxy] team. It'll be down to the manager to see how I feel on the day of the game, and I'll do everything right and do everything that is best for the team."
