The two are among 140 players trying out for a potential spot in the XFL, set to launch in the spring of 2020.
Richardson, 29, was taken with the No. 3 overall pick by the Browns in 2012 NFL draft. However, he lasted just over a year in Cleveland before he was traded to the Colts for a first-round pick.
The Raiders elected to sign him to a two-year, $3.85 million contract that included $600,000 guaranteed back in 2015 only to release him during roster cuts.
Richardson worked out for the Ravens a few years ago but had to get in shape before the team later signed him to a one-year deal worth $675,000. However, he was waived soon after.
Richardson sat out two seasons before signing on with the Roughriders in 2017. He was suspended by the team in 2018.
In 2019, Richardson played for the Birmingham Iron of the now-defunct AAF. Through February he had 59 carries for 145 rushing yards and six touchdowns.
In 2014 with the Colts, he ran for 519 yards on 159 carries (3.3 YPC) to go along with 27 receptions for 229 yards receiving and three touchdowns.
Cook, 25, was taken by the Raiders in the fourth round of the 2016 NFL Draft. He was entering the third year of his four-year, $2.959 million contract and set to earn a base salary of $630,000 when the Raiders waived him coming out of the preseason.
Oakland waived Cook at the start of the 2018 season and he later signed on to the Panthers’ practice squad. However, Carolina released Cook in October and he later signed on to the Bengals’ practice squad.
Cook signed a futures deal with the Lions at the start of 2019. The Lions waived Cook in June.
