Nelson, 26, is a former seventh-round pick of the Broncos back in 2014. He played out the final year of his four-year, $2,268,600 contract and made a base salary of $690,000 for the 2017 season before signing one-year, $1.6 million contract with the Eagles this past March.
Unfortunately, the Eagles elected to release Nelson in a move that cleared $1 million of available cap space.
He signed on with the Falcons but was cut loose last month. The Raiders hosted him for a workout in recent weeks but did not sign him to a contract.
In 2017, Nelson appeared in five games for the Broncos and recorded four tackles and no sacks.
