Obafemi Martins' missed Seattle Sounders training on Thursday while undergoing X-rays for an undisclosed ailment, casting into doubt his availability for Saturday's game against the Vancouver Whitecaps. Sounders head coach Sigi Schmid was evasive when asked about the specific injury, only saying "I'm being Bruce Arena."

"He's had a little bit of a complaint but we want to see with the X-ray and we'll make a determination tomorrow," Schmid said on Thursday, according to the Seattle Times.

Losing Martins would obviously be a blow to the Sounders. Martins has already scored six goals this season, which is just one fewer than co-MLS leader Clint Dempsey. Dating back to last year, Martins has scored 23 times, more than any player other than Bradley Wright-Phillips (32).

Martins' absence would also mean the Sounders would be going to Vancouver with a less-than-full-strength squad for the third straight time. On May 24, 2014 the Sounders pulled out a 2-2 tie despite missing Clint Dempsey, DeAndre Yedlin and Chad Marshall. On their trip, July 5, 2014, they lost 1-0 without the services of Dempsey, Martins, Yedlin and Osvaldo Alonso. Those kinds of absences have only contributed to the Sounders' struggles at BC Place, where they've gone 0-2-3.
