Stalberg was injured Tuesday night in the first period of Nashville's preseason game against the Tampa Bay Lightning.
The Predators signed Stalberg to a four-year, $12 million contract during the summer. He won the Stanley Cup with the Chicago Blackhawks last season, scoring 23 points on nine goals and 14 assists in 47 regular season games. He also had three assists in 19 games in the Stanley Cup Playoffs.
You could see out there that everybody was willing to compete, to sacrifice, even blocking shots to the end. Even in the third when we were up 5-0, guys were still working hard and blocking shots That's a nice feeling also for the future.
