It felt like a captains practice: Patrice Bergeron was back on the ice.

The Bruins’ No. 1 center and franchise cornerstone, who is entering his 15th NHL season, was on the ice for the start of Friday’s informal workout at Warrior Ice Arena.

Bergeron had groin surgery in June, and coach Bruce Cassidy told the Globe last week that he will be limited when camp opens Sept. 10, and is likely to miss some preseason games. But Bergeron participated in about 15 minutes of light drills Friday, then exited before a group of 20 skaters ran through three-on-three and four-on-four scrimmages.

Defenseman Torey Krug, who broke his left ankle May 4 — the same injury that felled blue liner Brandon Carlo about a month earlier — skated with Bergeron and fourth-liner Noel Acciari, who had groin surgery May 24.
