Practice is open to the public and the media on Tuesday for the first time of the 2013 season as Organized Team Activities (OTAs) continue in Green Bay.

OTAs mark the beginning of Phase Three of the offseason, in which the team can practice together in a team environment. It follows Phase One of strength and conditioning and Phase Two of individual position workouts.

The session begins at 11:30 a.m. at Clark Hinkle Field on the west side of the Don Hutson Center. Typically the team has used Ray Nitschke Field for OTAs  in the past, but will move over to Hinkle as Nitschke is being prepared for training camp.

One OTA practice per week is open to the public in Green Bay, each Tuesday on May 21, 28 and June 11. They'll also have two minicamp practices open on June 4 and 5.

Following practice, head coach Mike McCarthy will hold a press conference that will be broadcasted live on the team's official website at 1:35 p.m. CT.

Also on Tuesday, the NFL's Spring Meetings take place in Boston, where presumably team president Mark Murphy and others in the Packers organization are representing Green Bay.

Among the topics being discussed are moving the NFL Draft and other events in the league's offseason calendar such as the Combine and the start of the league year. They're also discussing potential changes to the Pro Bowl.

One thing that will be decided with certainty on Tuesday will be the host sites of Super Bowl L (50) and LI (51). San Francisco and Houston, respectively, are expected to be the winning cities for the upcoming Super Bowls held in 2016 and 2017.
