Roger Torres did not travel with the Philadelphia Union to Oregon because of an injury, Philly.com's Jonathan Tannenwald reported on Twitter.
Tannenwald, The Goalkeeper's editor and main writer, said that Torres, 20, suffered an ankle injury while the team was in Costa Rica, in the third stage of its preseason tour, and won't face the Portland Timbers.
"Peter Nowak told me that it isn't a huge injury but with the turf and the weather in Portland he thought it better that Torres not travel," Tannenwald said in a follow up tweet.
Without Torres in the lineup or on the bench the Union will most likely rely heavily upon Freddy Adu and one, or both, of Gabriel Farfan and Michael Farfan to provide creativity out of the midfield.
Chris Albright is also expected not to play Monday, as the veteran defender is listed as doubtful in MLS's Injury Reportwith a left groin strain.
