Marlowe, 27, wound up signing a three-year, $1.575 million contract with the Panthers as an undrafted free agent out of James Madison back in 2015. The Panthers later waived Marlowe with an injury designation and he later reverted to injured reserve before being waived with a settlement soon after.
The Bills signed him to their practice squad in 2017 and brought him back on a futures contract. He was waived coming out of the preseason and has been on and off of their roster ever since.
In 2019, Marlowe appeared in nine games for the Bills and recorded 10 tackles and a pass defense.
