Having gained international approval, Eagleson then convinced the NHLPA's players to support the tournament with promises of increased pension contributions resulting from their participation. The NHL's owners supported the concept after agreeing that half of the proceeds from the games would go to them. Some teams remained uneasy, however. The Philadelphia Flyers were afraid their players might suffer injuries in the tournament and vowed that no player from their roster would be permitted to play. They were convinced to back down on their threats after being promised two games would be played in Philadelphia with the Flyers receiving their share of the revenue. Though the tournament was held in September so as not to interfere with the NHL season, league president Clarence Campbell remained skeptical of the tournament's viability, calling it "wasteful".
