The club also announced it was placing Barth on the reserve / non-football injury list instead of injured reserve. The Bucs said Barth suffered the injury Friday.
To replace Barth, the Buccaneers tabbed one of the top veteran placekickers left in free agency, adding former Giant Lawrence Tynes.
The 35-year-old Tynes connected on a career-best 33 field goals in 39 attempts in 2012 for New York, which signed kicker Josh Brown in March.
“We are disappointed to lose a productive player like Connor, but are very fortunate to be able to sign an experienced kicker at this time of year,” Buccaneers GM Mark Dominik said, according to the club.
Barth, 27, connected on 28-of-33 field goals in 2012. He signed a four-year, $13.2 million contract last May, per Rotoworld data.
