Though the two rookies were sent down to Rochester on Tuesday, both are expected to be back on the Sabres' roster Thursday, when Buffalo opens the season at Pittsburgh. The demotions were part of a series of moves the team made to be under the NHL's $81.5 million salary cap.
Buffalo placed defensemen Zach Bogosian, Brandon Montour and Matt Hunwick and goalie Ukko-Pekka Luukkonen on injured reserve. Bogosian is out indefinitely while recovering from hip surgery, while Montour is out with a hand injury.
Hunwick is expected to miss the entire season with a neck injury.
