LOS ANGELES, Calif -- Rafa Marquez is back in full training and on course to feature for Mexico in Sunday's CONCACAF Cup against the United States, according to El Tri's sporting director Santiago Banos.

"Rafa joined the group [in training] yesterday and he is very motivated like all of them," Banos told press outside the team hotel in Hollywood on Thursday.

"Most likely he'll be ready, that is what we are hoping."

But while 36-year-old veteran Marquez, who had been a doubt with a groin injury, is set to play, there are concerns over goalkeeper Jonathan Orozco, who stayed back in Mexico due to family problems. Banos confirmed the Monterrey goalkeeper may miss the match on Saturday in the Rose Bowl.
