Washington Redskins quarterback John Beck walks away after talking to reporters outside the team's football training camp at Redskins Park in Ashburn, Va., Tuesday, July 26, 2011, the day after the NFL lockout ended.

The gates were up, training facilities were open and NFL players went back to work.

Now, they need to get ready for the season in a hurry.

After a lockout that lasted 4½ months ended Monday with an agreement between the NFL and its players, teams' facilities were buzzing with activity Tuesday. Players all around the league were allowed back in to meet with coaches, work out, take physicals and receive playbooks.

Teams were also allowed to sign their drafted players and undrafted free agents, and negotiate with free agents in what will likely be a flurry of activity unlike what the league has ever seen. Players such as Nnamdi Asomugha and Santonio Holmes will soon find out where they're going — or staying — as free agency began.
