Sabres prospect Olivier Nadeau out 4-6 months after shoulder surgery

‘The Sabres signed Nadeau to three-year, entry-level contract in May, but the NHL’s development agreement with the Canadian Hockey League, which governs the three major junior leagues in Canada, bars players from competing in the American Hockey League until they turn 20 years old. Nadeau won’t turn 20 until January 2023, so he’s unlikely to start his professional career with the Rochester Americans until next spring.’
