The tender would earn the defensive end approximately $2.7 million in 2012. The high tender means the Bucs would receive a first-round draft pick if another team signs Bennett.
Bennett joined the Bucs in 2009 and has gradually grown into a steady player. He started 10 games last season and produced a career-high four sacks.
According to a source, the Bucs have also sent tenders to their two exclusive-rights free agents -- running back LeGarrette Blount and receiver Preston Parker. Each of those tenders is worth $540,000.
The Bucs also placed the right-of-first-refusal tender on offensive lineman DeMar Dotson, a source said. That tender is expected to be about $1.26 million. Tender numbers will be finalized before the start of free agency March 13. The Bucs would not receive compensation if Dotson signs with another team.
The Bucs placed the franchise tag on kicker Connor Barth on Monday. That tender is expected to be worth about $2.65 million.
