Thomas hasn't played since leaving an Oct. 8 game against the Philadelphia Flyers with a groin injury, but he started skating with the team earlier this week.
Thomas won 196 regular-season games during his tenure with the Bruins and another 29 in the Stanley Cup Playoffs. He led the team to a championship in 2011, a season in which he won the Vezina and Conn Smythe trophies.
I definitely think going back down helped me, I had a lot of confidence down there, I played a lot of minutes and I think that helped me a lot. With the 37 games up here, that gave me experience as well. I know what it takes to play in the NHL and now it's time for me to show that I'm capable of being a full-time NHL player.
