Flames defenseman Travis Hamonic became the first NHL player to opt out of this summer's restart.

Calgary GM Brad Treliving announced Hamonic's decision Friday night, just hours after the NHL and NHLPA officially agreed to move forward with a 24-team tournament, scheduled to begin Aug. 1.

"Earlier this evening Travis called me to inform us that he has decided to opt out of the NHL return to play program," Treliving said in a statement.
