The news was reported via the Penguins' Twitter account on Tuesday.
The hope is that Martin, who missed the last two games for the United States against Canada and Finland at the Olympics, will be ready to play when the Stanley Cup Playoffs begin in mid-April. Martin has two goals and 12 points in 33 games for the Penguins.
The Penguins also revealed that goalie Tomas Vokoun, who hasn't played a game this season after developing blood clots in his leg in September, has been cleared to practice with the team. There is no timetable for his return.
