EDEN PRAIRIE, Minn. (AP) The Minnesota Vikings are having injury trouble in the middle of their offensive line.

Center John Sullivan and right guard Vlad Ducasse were hurt on the same play Sunday in the first quarter at Buffalo, and neither returned to the game. Sullivan suffered a concussion. Ducasse hurt his knee. Coach Mike Zimmer said Monday the team will learn more about their status as the week progresses.

Ducasse was already filling in for Brandon Fusco, whose season is over because of a torn pectoral muscle. Backup tackle Mike Harris replaced Ducasse at guard and Joe Berger stepped in for Sullivan at center.

The Vikings rushed for 158 yards against the Bills, who were leading the league in that category. They allowed five sacks, though.
