The Sabres knew they'd need depth on defense at some point, and that point is now. Craig Rivet had knee surgery today and is out at least two weeks.
The captain had three assists in the first six games, and he will give way to Nathan Paetsch. Paetsch has shown flashes of both toughness and offensive ability in the past, and he'll need to continue. In fact, in Rivet's absence, he'll need to do it better.
The Sabres are on the ice right now in HSBC Arena. The defensive pairings are Paetsch-Teppo Numminen, Henrik Tallinder-Toni Lydman, and Jaroslav Spacek-Andrej Sekera.
Is that good enough?
