Trinidad and Tobago goalkeeper Andre Marchan sustained a concussion late in his team's 7-1 loss to Mexico in CONCACAF Olympic qualifying Friday night, a match that took a toll on both sides.

Marchan and Mexico's Nestor Calderon collided in the 77th minute as Calderon was trying to latch on to a long ball. Marchan charged forward to punch the ball away, and was kicked in the left side of the head as Calderon extended his right leg to reach for the ball.

"He had a mild concussion," manager Angus Eve said after the match. "He said he was stomped by the guy in the head as he was trying to clear the ball. But he's feeling much better. He's with the team doctor at the moment."

Whether Marchan will play Sunday against Panama is an open question.

"It's too soon to tell," Eve said. "After we go back to the hotel, we'll take a look at him. He may have to go for a scan. Then we'll know what's exactly happening with him."

The injury appeared to bother Marchan for the rest of the match. He held his head a several times in the closing moments, and conceded two goals in the final five minutes.

After Marchan dived to stop Javier Cortes' cross along the right end line in the 85th minute, Marco Fabian converted the rebound for his third goal. Then in the 90th minute, Cortes scored on an eight-yard shot through Marchan's legs.

When the match ended, Marchan sat near the left goal post, received attention from a trainer and was quickly escorted to the locker room before both teams left the field.
