Rawls, 25, wound up signing on with the Seahawks as an undrafted free agent out of Central Michigan back in May of last year. He played out the final year of his three-year, $1.59 million rookie contract but was not tendered a restricted offer by the Seahawks.
Rawls signed on with the Jets this past March but was among their final roster cuts coming out of the preseason. The Bengals signed him to a contract a few weeks ago only to cut him loose earlier in the week.
In 2017, Rawls appeared in 12 games for the Seahawks and rushed for 157 yards on 58 carries (2.7 YPC) to go along with nine receptions for 94 yards receiving and no touchdowns.
Robinson, 26, is a former seventh-round pick of the Lions back in 2015. The Lions traded him to the Panthers for a conditional 2020 seventh round pick coming out of the preseason.
Robinson was in the final year of his four-year, $2.338 million contract and set to make a base salary of $705,000 for the 2018 season when the Panthers waived a few weeks ago.
In 2018, Robinson has been active for two games.
