Jones was signed by the Raiders earlier this offseason to compete for the backup quarterback position. He was cut to make room for TE Erik Swoope.
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.
Jones later signed with the Jaguars in October but was released a couple of weeks later.
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.
