The midfielder was taken to hospital after possibly breaking his collarbone.
There are plenty of reasons to think the Seattle Sounders have the deck stacked against them heading into Wednesday's decisive CONCACAF Champions League quarterfinal match against Club America. But the Sounders' task did get a little bit easier after Saturday's Liga MX results.
Not only did Club America prove themselves perfectly mortal -- taking a 4-1 loss to UANL Tigres -- but they also lost midfielder Rubens Sambueza to what the team fears may be a broken collarbone. Sambueza has been one of America's top players this year, logging three goals and an assist in seven appearances.
