Tabor, 24, was drafted by the Lions in the second round out of Florida back in 2017. He was entering the third year of his four-year, $4.82 million rookie contract when Detroit cut him loose during final roster cuts in 2019.
He signed on with the 49ers’ practice as a free agent in October of last year and eventually re-signed to a futures contract this offseason. However, San Francisco wound up waiving him with a non-football injury designation this past July.
In 2018, Tabor appeared in 12 games for the Lions, recording 28 total tackles, no interceptions and no pass defenses.
