EDEN PRAIRIE, Minn. -- The NFL may be headed back to a lockout.

A federal appeals court in St. Louis late Friday granted the owners' request to temporarily put on hold U.S. District Judge Susan Nelson's ruling that lifted the lockout.

The order came only hours after teams opened their doors to players and some of the basic football operations began, and it came as the second round of the draft was under way. There was no immediate word from the NFL on whether the lockout would resume.

The 8th U.S. Circuit Appeals Court said that it would grant the stay while considering the league's appeal of the Nelson's injunction.

The 2-1 decision included a lengthy dissent.
