Former two-time Pro Bowler has been released just before the NFL offseason begins

The NFL veteran is hitting the open market.

Doug Martin has been cut from the Tampa Bay Buccaneers. Because of their roster decision, he'll be open to sign with any team after 4 p.m. on the day he's released. The start of NFL free agency (considered legal tampering) doesn't officially begin until March 12.

Martin missed the first four games of the 2017-18 season after violating the NFL's drug policy. He played the first six seasons of his NFL career with the Tampa Bay Buccaneers.

Martin rushed for more than 4,000 yards and 26 touchdowns over 65 starts.

He is a two-time Pro Bowler.
