Tapper, 26, is a former fourth-round pick of the Cowboys back in 2016. He was in the third year of his four-year, $2.95 million contract and set to make base salaries of $630,000 and $720,000 over the next two years when the Cowboys cut him loose in 2018.
Dallas later re-signed Tapper to their practice squad, but was released a few days later. From there, he signed a futures contract with the Jets before being placed on the non-football injury list last year.
In 2017, Tapper appeared in two games and recorded three tackles and a sack for the Cowboys.
Hatcher, 25, originally signed on with the Raiders as an undrafted free agent out of Arkansas back in 2017. He was waived coming out of the preseason, but later added to the Raiders’ practice squad.
From there, Hatcher had brief stints with the Lions and Packers before the Jets signed him to their practice squad late last season. He returned to New York on a futures contract.
During his college career at Arkansas, Hatcher caught 130 passes for 1,866 yards receiving and 19 touchdowns over the course of five seasons and 47 games.
