Jones, 24, is a former second-round pick of the Patriots back in 2016. He was entering the third year of his four-year, $4 million contract that included a $1.1 million signing bonus and was set to make a base salary of $814,246 this season when the Patriots waived him coming out of the preseason.
The Ravens later signed Jones to their practice squad.
Jones landed on the season-ending injured reserve last year after sustaining torn ACL and meniscus injuries.
In 2016, Jones appeared in 10 games and recorded seven tackles, no interceptions or pass defenses, 180 kick return yards and 46 punt return yards.
Barner, 27, is a former sixth-round pick of the Panthers back in 2013. He spent just over a year in Carolina before he was traded to the Eagles in return for a conditional seventh-round pick that did not meet the qualifications.
The Eagles waived him with an injury settlement at the start of the 2014 season and later brought him back on a future/reserve contract. Philadelphia didn’t tender him a restricted offer a few years ago and he later signed a one-year contract with the Chargers.
Barner returned to the Eagles a few weeks into the 2017 season. The Panthers signed him to a contract back in May but cut him loose at the start of the season and he signed on with the Patriots a week later.
In 2017, Barner appeared in 13 games for the Eagles and rushed for 57 yards on 16 carries (4.4 YPC) to go along with five receptions for 56 yards and one touchdown. He also contributed 194 kick return yards and another 240 punt return yards.
