Gettis, 30, is a former fifth-round pick by the Redskins in the 2012 NFL Draft. He had stints with the Steelers and Raiders during the three years he spent with the Giants.
New York brought Gettis back on a futures contract in 2017 only to cut him loose in November. The Buccaneers later signed him to a contract in the final few weeks of the season, but declined to tender him a restricted offer last offseason.
Even so, Gettis returned to the Buccaneers a few weeks later. He was cut early in September 2018.
In 2016, Gettis appeared in three games for the Giants, starting one.
