The Tampa Bay Buccaneers released quarterback Josh Freeman on Thursday league sources told ESPN NFL Insider Adam Schefter.

The team tried to trade the quarterback but wasn't able to find a taker. By releasing Freeman the Buccaneers are obligated to pay the quarterback all $6.2 million he was owed in remaining salary this season.

Freeman who was drafted 17th overall by the Buccaneers in the 2009 draft was benched in favor of rookie Mike Glennon prior to the Bucs' 13-10 loss to Arizona this past Sunday. In 60 career games Freeman has thrown for 13534 yards 80 touchdowns and 66 interceptions.

The NFL Players Association is also investigating how Freeman's presence in Stage 1 of the league's substance-abuse program became public earlier this week. On Tuesday Buccaneers coach Greg Schiano was asked by reporters if he was the source of the information and said "absolutely not."

Freeman was fined twice in the last month for conduct detrimental to the team according to an SI.com report. The website reported he will appeal the fines.
