Jones was a fourth round pick by the Steelers in the 2013 draft. He spent five seasons with the team and shortly after the Raiders made the trade to acquire Antonio Brown this offseason, they added his former teammate Jones as well.
The team had already added free agent Mike Glennon and brought back Nathan Peterman. For two months, the team had four QBs on the roster with those three QB competing to be the backup to Derek Carr. Jones apparently lost that battle. Now the 30-year-old is seeking his future outside the NFL.
There are eight XFL teams formed, so the remaining seven starting QBs very likely will come from those QBs which are waived on August 31 in final 53-man roster cutdowns and not claimed by any other clubs.
