The Scottish designated player looks likely to miss this weekend's game with a hamstring injury after being spotted watching tennis in Vancouver.
The Scottish designated player is listed as questionable for the road game at Buck Shaw Stadium due to a hamstring complaint, but took in Canada’s Davis Cup tennis tie with Italy on Friday at the University of British Columbia alongside third-string goalkeeper Simon Thomas and the team’s equipment manager.
If Miller misses out, it will be a blow for the ‘Caps, who have struggled without him in the starting lineup. Two games ago Vancouver fell to the Houston Dynamo 2-1 while the player was representing Scotland in World Cup qualifying action.
Then, last weekend against the Columbus Crew, Whitecaps head coach Martin Rennie felt his countryman couldn’t play a full 90, so used him as a substitute in the 58th minute.
Miller scored shortly after in a 2-1 defeat, but it was hoped he’d be able to play from the start this weekend against the Earthquakes -- something that looks unlikely now.
