The Saskatchewan Rush won their last regular season game of the year Saturday, taking the Knighthawks 13-9 in Rochester.
The win means Rochester is eliminated from playoff contention while Saskatchewan finishes second in the overall standings.
Both the Rush and the Buffalo Bandits hold 13-5 records, but Buffalo held the tie-breaker advantage to finish first because of an overtime win in Saskatchewan earlier in the season.
The Rush locked up first in the west division last month, which means the team will sit out the first round of playoffs. Colorado will host Calgary for a one-game semifinal showdown in the division, and Saskatchewan will face the winner in the best-of-three west final.
Buffalo has the opening-round bye in the east and will face the winner between Georgia and New England.
