NFL free agency begins on Tuesday afternoon. At 4 p.m. ET, players without a team can officially sign new contracts.

In addition to players who saw their contracts come to an end in 2014, other stars will soon become free agents, as they are released. Teams will be forced to make difficult decisions and cut some of their top players, because of salary cap restrictions.

Heading into the start of free agency, the Oakland Raiders have the most money to spend. They lead the league with more than $60 million in cap space, followed by the Jacksonville Jaguars and Cleveland Browns. The Dallas Cowboys and New Orleans Saints have the least amount of money to spend.

As NFL teams look to make moves, below are some updates on free agents and other players that could be wearing different uniforms next year.

Michael Johnson

It didn’t take long for Johnson to sign with a new team. After spending the first five years of his career with the Cincinnati Bengals, the defensive end is headed to the NFC. According to ESPN’s Josina Anderson, Johnson has received a five-year deal worth $43.75 million from the Tampa Bay Buccaneers. Johnson had just 3.5 sacks in 2013, after recording 11.5 sacks the previous year.

Adam Vinatieri

At 41 years old, the kicker isn’t finished playing professional football. He has agreed to stay with the Indianapolis Colts for another two seasons, after scoring 139 points in 2013. If Vinatieri finishes out his contract with the Colts, he’ll have played as many seasons in Indianapolis as he did with the New England Patriots.

Owen Daniels

The tight end is no longer a member of the Houston Texans, following eight years with the team. Houston, which had the worst record in the NFL last season, cleared $4.5 million in cap space with the move. The tight end missed 11 games in 2013 because of injuries.

Darrelle Revis

The cornerback is still a member of the Tampa Bay Buccaneers, but that may not last for long. reports that Revis will either be released or traded by the organization. Revis will likely be cut, if the Bucs can’t find a deal for him by 4 p.m. ET on Wednesday. At that time, Revis is set to make a $1.5 million roster bonus. Freeing themselves of Revis’s contract would save Tampa Bay $16 million in cap space.

Jared Allen

The defensive end joins the list of free agents that will have a new home in 2014. Jason La Canfora of CBS Sports reports that Allen won’t return to the Minnesota Vikings. The 31-year-old has been linked to the Denver Broncos and Green Bay Packers. He’s recorded at least 11 sacks in seven straight seasons.
