Chicago leads the best-of-seven series three games to two.
Toews was held out of the third period in Game 5 on Saturday night with an upper body injury, but participated in the morning skate Monday morning at TD Garden in Boston. He said he is good to go as the Blackhawks try to win the Stanley Cup for the second time in four seasons.
"I feel great. I'm excited. There's no question about where I am physically," Toews said to NHL.com. "I think that was just the coaches being cautious, not letting me get back on the ice in the third period the other night. We got to the point where I was ready to go again. I'll be ready to go tonight."
Toews took a hit from Bruins defenseman Johnny Boychuk in the second period during Game 5, but continued to play.
"It was a couple hits that I took that I guess the coaches thought I wasn't ready to play in the third period," Toews said, declining to discuss the specifics of the injury. "Obviously you always want to bounce back. It is a physical game. There are no worries there. The coaches were confident we could win the game while making sure I wasn't risking anything. I feel 100 percent and the coaches are aware of that."SI WIRE: Maple Leafs acquire Jonathan Bernier in three-player trade
