WILMINGTON, Mass. — Today was the first day of Bruins rookie practice at Ristuccia Arena in preparation for the rookie games against the New York Islanders Wednesday and Thursday at TD Garden.

The Bruins, by the way, say they’ve sold north of 7,000 tickets for each game so far.

Here’s a look at the line of Joe Colborne centering Jordan Caron and Lane MacDermid during one drills.

And this is phenom Tyler Seguin going to work with his linemates Jared Knight and Jamie Arniel.
