Barth, who just received a four-year contract last offseason, was injured during a charity basketball game.
The 27-year-old Barth had surgery Monday and will be placed on the reserve/non-football injury list.
“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 General Manager Mark Dominik said. “Lawrence and his agent, Ken Harris, had other standing opportunities, but we are pleased that they thought this was the right place for Lawrence to continue his career.”
Tynes has played nine seasons in the NFL. The 35-year-old has been part of two Super Bowl winning teams with the New York Giants.
Last season for the Giants, Tynes hit 33 of 39 field goal attempts and finished the year with 145 points, the second most in the NFL.
