Though the labor deal is not yet finalized, the Sabres are preparing for the start of training camp, which could open as early as Sunday.
Myers, the NHL's 2010 rookie of the year, is Buffalo's top defenseman and entering the first of a seven-year, $38.5 million contract extension he signed in September 2011. He's set to make $12 million this season.
Myers' importance to the Sabres was evident last season, when he missed 27 games, including 19 straight with a broken hand. Buffalo went 9-11-7 without him, and 30-21-4 with him in missing the playoffs by finishing ninth in the Eastern Conference standings.
He finished with eight goals and 15 assists in 55 games.
Other new arrivals at practice were backup goalie Jhonas Enroth and defensemen Andrej Sekera and Adam Pardy.
Enroth spent part of the lockout playing in his native Sweden. Pardy was acquired along with center Steve Ott by Buffalo in a trade that sent center Derek Roy to Dallas last summer.
Starting goalie Ryan Miller is expected to join his teammates on Friday.
Retired Sabres Andrew Peters and Jay McKee are informally overseeing the sessions. They have consulted with the Sabres coaching staff regarding drills and what to focus on during practice.
