NHL Lockout Looms: Owners and Players at Odds Over Revenue Share In a move that has left fans of the National Hockey League on edge, a looming lockout is threatening to cancel the upcoming season. Tensions between owners and players have been escalating, with both sides unable to come to an agreement on revenue sharing. The current collective bargaining agreement is set to expire on September 15, and if a deal is not reached, the 2009-2010 season could be in jeopardy. As the clock ticks down, hockey enthusiasts are holding their breath, hoping that a compromise can be reached to save the season.
