Jones, 29, is a former fourth-round pick by the Steelers in the 2013 NFL Draft. He finished out the final year of his four-year rookie contract and returned to Pittsburgh on a two-year contract in 2017.
However, the Steelers elected to release Jones coming out of the 2018 preseason as they trimmed their roster down to 53 players. He had a brief stint with the Jaguars last year before signing on with the Raiders during the offseason.
Unfortunately, Oakland cut Jones loose a few weeks ago.
In 2017, Jones appeared in three games for the Steelers and recorded 23 completions on 28 attempts (82.1 percent) for 239 passing yards, one touchdown and one interception.
Michael, 28, is a former second-round pick of the Seahawks back in 2013. Seattle traded him to the Cowboys for a conditional seventh-round pick in 2015.
Michael had brief stints with the Redskins, Seahawks and Packers before signing on with the Colts in 2017. Indianapolis elected to bring him back on a one-year contract last year only to cut him loose a few weeks into the preseason.
In 2018, Michael has appeared in two games and rushed for nine yards on two carries and no touchdowns.
Ripkowski, 26, is a former sixth-round pick out of Oklahoma by the Packers back in 2015. He is entering the final year of a four-year, $2,386,396 contract and set to earn a base salary of $705,000 this season when he was waived at the start of the 2018 season.
Ripkowski wound up sitting out the entire 2018 season before signing a futures contract with the Chiefs this past January only to cut him loose last month.
In 2017, Ripkowski appeared in all 16 games for Green Bay and recorded five rushing attempts for 13 yards to go along with seven receptions for 39 yards receiving and no touchdowns.
