Corner kicks: Schweinsteiger left the Montreal game in the 79th minute with a right thigh injury. Paunovic said the German midfielder did not practice Tuesday or Wednesday for precautionary reasons. His status for Saturday's game is questionable. "We want to avoid any kind of injury during the week," Paunovic said. "We are obviously very cautious with that and have to evaluate it on a daily basis." ... Midfielder David Accam sat out Saturday's win with an ankle injury but is expected to play Saturday. ... Polster saw his first action since Aug. 12 in Montreal after sitting out three games, and Brandon Vincent played for the first time since July 5 after missing seven.
