Vancouver Whitecaps have lost key defender Andy O'Brien to a hamstring injury.
O'Brien was hoping the problem is not as bad as first feared: "I just went to pinch the ball and that was it, gone.
"I felt 'bang' in my hamstring.
"Hopefully, it's more nerve than muscle. We'll just have to wait and see Monday. Just keep some ice on it and see how it is."
Whitecaps head coach Martin Rennie admitted it was a massive blow to lose O'Brien.
"When we lost Andy O'Brien, the game opened up and we were disjointed," said Rennie. "That was the turning point in the game. Andy organizes and helps (Johnny Leveron) a lot, helps him be in good positions.
"The reality is that when you lose the players we've lost in that position, it's hard to replace them. We've done really well with it up until this point, but (Saturday) that was the first time it really cost us."
