A day after a federal judge ended the NFL’s 45-day lockout, small groups of players showed up at team facilities Tuesday but were told they would not be allowed to train or work out.

Most players left in a matter of minutes on a day with more questions than answers to the fight between players and owners over how to divide $9 billion in revenues.

The league said players should be “treated with courtesy and respect” if they show up at team headquarters. But the NFL said it needs “a few days to sort this out” before “football activities” can take place.

Little was clear as both sides essentially made up the rules as they went along.

“It’s very chaotic for the teams right now,” agent Drew Rosenhaus said. “It’s not chaotic for the players. Our position is the lockout is over, free agency should begin, signings should begin, offseason workouts should begin, everything should be going on. The longer the NFL doesn’t do that and drags this out, the more there are concerns of collusion and violations of antitrust laws.”
