Penguins beat Sabres 3-1 as Bryan Rust exits preseason finale

Pittsburgh beat Buffalo 3-1 in their preseason finale, with Sidney Crosby and Ville Koivunen scoring before Nick Robertson added an empty-net goal. Bryan Rust left 20 seconds into a second-period shift, and the Penguins announced he would miss the rest of the game.

The Sabres scored their only goal on a third-period power play. Buffalo challenges erased two Penguins goals in the second: Evgeni Malkin's for goalie interference and Rakell's because Crosby was offside on the entry.
