The LA Galaxy are awaiting tests on Giovani dos Santos after the Mexican star was taken off at halftime of the Sunday night's 1-0 loss to the Portland Timbers with a right leg injury.
Dos Santos picked up the knock during a first half that saw the Galaxy go down to 10 men after Jelle Van Damme's dismissal.
Galaxy coach Curt Onalfo said after the match that dos Santos would be evaluated on Monday.
"Gio has a slight strain to his hamstring or just tightness," said Onalfo, who replaced dos Santos with Ema Boateng at the half. "We'll know more tomorrow, but he couldn't go in the second half, so we had to make that change."

Diego Chara scored in the eighth minute for his seventh career goal in seven MLS seasons to power Portland, which went winless on the road last season. The Timbers won for the first time away from home since beating the Galaxy on Oct. 8, 2015.
The Galaxy opened the season with two defeats for the first time since 2001. They have lost three of their past four regular-season home games after a 15-match home unbeaten stretch.
LA, already without several key players, was reduced to 10 men in the 34th minute after Van Damme received two yellow cards within a three-minute span.
Gyasi Zardes, Ashley Cole and Robbie Rogers were all out with injuries, while Jermaine Jones and Dave Romney were on suspension.
