Vancouver, BC (SportsNetwork.com) - A pair of clubs looking to stop runs of poor form will clash on Saturday when the Philadelphia Union travel to BC Place to battle Vancouver Whitecaps FC.

The Whitecaps have been the early surprise package of the season with 17 points through their first 10 matches, but have hit a little bit of a bump in the road. Carl Robinson's club has gone winless in four of their last five matches.

Since earning a 1-0 win over Real Salt Lake on April 18, the Caps fell to a 2-1 defeat at home to D.C. United and settled for a scoreless draw at Providence Park against Cascadia rivals Portland Timbers.

The best chance for either side came in the 29th minute when Vancouver defender Pa Modou Kah was whistled for a hand ball in the penalty area, resulting in a spot kick for the Timbers.

Darlington Nagbe stepped up to take and ripped it low to the right, but smashed it off the post as the chance went begging.

Just moments later the Timbers had another golden opportunity when Max Urruti found some space in the box and got a free header away from eight yards out but it flew over the bar.

The home faithful got a boost in the 52nd minute when playmaker Diego Valeri came on as a substitute looking to influence the match in his team's favor.

But neither side could find a dramatic winner through four minutes of added time and were forced to settle for a share of the spoils.

Philadelphia, meanwhile, is looking for just its second win of the season as the club has just six points through 10 matches. Last time out, it was the same old story for the Union as the team fell to a 1-0 loss to Toronto FC at PPL Park.

"Another disappointing loss," head coach Jim Curtin said. "In the second half I was proud of the effort that the guys put in. I thought that they pushed the game and they pushed the tempo. They had a couple chances that were blocked in front of goal. It's not a lack of effort. They are working very hard."

The Union are also likely to have goalkeeper Rais M'Bolhi back between the sticks on Saturday as the Algerian international returned to the team following some time away and participated in training earlier in the week.

Things then took a strange turn for the Union's goalkeeper situation when both backup goalkeeper, John McCarthy and Andre Blake, were both injured in training during the same session.

"I'd say the timing is beyond crazy," Curtin said during his press conference with local media. "I've never seen two goalkeepers get hurt in one training session. I've never seen two goalkeepers get hurt in a season, let alone 45 seconds apart."

Blake, who hasn't seen action this season due to a torn meniscus, will miss around 4-6 weeks with the same injury, while McCarthy is out with concussion symptoms.

The only meeting between the sides at BC Place occurred on July 27, 2013. Philadelphia took a 1-0 win thanks to a late goal from Antoine Hoppenot.
