The NFL lockout is a thing of the past and teams are now busy getting their rosters in order as training camp nears in quick fashion.

Here's a look at what teams can do on what will be a very busy Tuesday.

At 9 a.m., Winter Park will open and players may report for physicals and voluntary strength and conditioning.

At 9 a.m., trading begins for the 2011 league year.

Rosters are expanded to the 90-man limit.

At 9 a.m., teams may negotiate with and sign their own drafted rookies and any undrafted rookie. Teams may have such players report to the club's facilities for physical examinations before signing.

All 2011 contracts signed on or after July 26 shall be binding upon the player and club when signed, but shall not become effective unless a CBA is ratified by the NFLPA (Aug. 4).

At 9 a.m., clubs may negotiate with, but not sign, or extend offer sheets to, their own unrestricted free agents, restricted free agents, exclusive rights players and franchise players and other clubs' UFAs, RFAs, non-exclusive franchise players and free agents.
