Davis was a somewhat surprising cut from Oakland, given that they traded for him a few months ago.
Davis, 26, is a former fifth-round pick of the Packers back in 2016. Green Bay traded him to the Raiders back in September for a sixth-round pick.
Daivs is currently in the final year of his four-year, $2.5 million contract and set to make a base salary of $720,000 for the 2019 season. He’ll be an unrestricted free agent in 2020.
The Raiders waived Davis on Monday.
In 2019, Davis has appeared in 11 games for the Packers and Raiders and caught eight passes for 111 yards receiving and no touchdowns. He has also rushed for 73 yards and a touchdown. As a returner, Davis has totaled 411 kick return yards and 112 punt return yards.
Zenner, 27, signed on with the Lions as an undrafted free agent out of South Dakota State back in 2015. He played out the final year of his three-year, $1.58 million contract but the Lions declined to tender him an offer as a restricted free agent and he tested the open market in 2017.
Detroit re-signed Zenner, but he was placed on injured reserve coming out of the preseason with a back injury. The Lions would later waive him with an injury settlement only to re-sign him in November.
Zenner returned to the Lions this past March but was cut loose at the end of August. He was with the Saints for a week before being released and picked up by Arizona. The Cardinals waived Zenner on Monday.
In 2019, Zenner appeared in one game for the Saints and three for the Cardinals, carrying the ball three times for minus-2 yards and catching two passes for 19 yards.
