Pekar recorded 36 points (14+22) in 33 games last season in his first year with the Colts before a broken collarbone ended his year early. He posted nine multi-point games during the 2018-19 campaign, which included five three-point games. He opened the slate with a season-long six-game point streak where he totaled 10 points (5+5) from Sept. 20 to Oct. 6.
He signed his entry-level contract with Buffalo last October after the team drafted him in the fourth round (94th overall) of the 2018 NHL Draft.
Pekar skated 13:42 and recorded three shots and four hits in Tuesday night's preseason game at Columbus.
Barrie's season begins on Friday against the North Bay Battalion.
