Raptors center Aaron Gray underwent a procedure Monday aimed at preventing episodes of a rapid heart rate that have kept the four-year veteran out of action so far this season. He’s expected to return in two weeks.

The procedure, known as an ablation, was performed at a Toronto hospital.

Gray, who signed a free-agent deal with the Raptors on Dec. 11, played in both of Toronto’s preseason games before being sidelined by a rapid heart rate.
