Obafemi Martins will undergo MRI to determine injury

Losing at home to the Portland Timbers in the U.S. Open Cup is bad enough, no matter the circumstances. But just how costly of a loss this proves to be is not yet entirely known. That's because the status of Obafemi Martins remains unclear after the Seattle Sounders forward was forced to leave the match around the 85th minute.

"It's in the groin area," Sounders head coach Sigi Schmid said, adding that Martins would need to undergo an MRI on Wednesday. "Is it an adductor? Is it a groin? We don't know."

The injury occurred when Martins collided with a Timbers player and then fell awkwardly. He was eventually wheeled off the pitch on a stretcher, but remained at Starfire.

Making Martins' injury doubly unfortunate was that it came shortly after the Sounders had used their third and final substitution and they were already playing a man down due to Brad Evans' 69th minute red card. By the end of the match, the Sounders were down to just seven players after Micheal Azira and Clint Dempsey were shown red cards in extra time.

Martins only recently came back from a broken nose and has also missed time with a fibial contusion this year. Despite being limited to 12 appearances across all competitions, Martins has scored eight goals to go along with four assists.
