Runners World has published an excellent Q&A Sarah Lorge Butler has done with Mike Smith. At the end of it, he talks about Galen Rupp's status:
SLB: spoke briefly to Ricky Simms, Galen Rupp’s agent, at the Trials, and he said Galen had surgery after the Marathon Trials. How is he doing?
MS: He had surgery on a hip that had been giving him trouble for years right after the marathon Trials, and that was a really long, slow rebuild. And fortunately, he’s getting healthy, but there was a long, long road, and he is still on it. So we’ll see. I mean he’s a competitor. If he can come back, he will. He had a pretty significant surgery.
