WILMINGTON, Mass. — The Bruins’ prospects opened the fifth-annual development camp at Ristuccia Arena today.

For the most part, the hour-long on-ice session went off without a hitch.

The only scare came late in the drills, when forward Jared Knight crashed into goaltender Michael Hutchinson. The netminder was down for a couple minutes before he skated off under his own power along with the trainer.

“If it was up to me, I would’ve went right back out for the rest of the skate,” said Hutchinson after practice. “But the training staff thought it’d be best if I just went off.”

Hutchinson said he saw Knight coming and braced himself for the hit, but there’s not much you can do when 5-foot-11, 202 pounds is coming at you almost at full speed. The Bruins completed the day with just two goaltenders.

Before hitting the ice, the Bruins’ prospects went through their off-ice testing.
