Sigi Schmid has confirmed that Marco Pappa will miss "at least the next two weekends" of MLS competition as he joins the Guatemelan national team in the Copa Centroamericana. The winner of that tournament will earn a spot in the Copa America Centenario in the summer of 2016, while the top four teams will qualify for the 2015 Gold Cup.

Pappa will return for the US Open Cup final in Philadelphia on Sept. 16, but won't take part in the Sounders' trip to take on Chivas USA on Sept. 3, nor is he likely to be available against visiting Real Salt Lake on Sept. 12.

As we saw on Saturday against the Colorado Rapids, Pappa's quick interchanges with the forwards and his deft longer passes are key to unlocking a tight defense, but the Sounders will have to look at other options as the left-footed midfielder represents his country.

Here's what Pappa told the Seattle Times about the call-up:

"Of course, it’s always an honor to go to the national team when they think about me," Pappa said. "You know how important it is to go represent your country no matter what. Like I said, I go with all my positives and hope we can do good with the national team. "I will also always be thinking about this team (Seattle) and hope they’re doing good."

Lamar Neagle and Kenny Cooper have been used on the wing this season, but neither offer the creativity of the Guatemelan. Tactical changes could be in store over the next two weeks as Sigi adjusts to his available personnel.
