Cornerback/kick returner Asa Jackson is back for his third stint with the Ravens.
The team signed Jackson, who they drafted in the fifth round in 2012, to fill a vacancy on the practice squad, following last Saturday's promotion of inside linebacker Patrick Onwuasor to the active roster.
The Ravens currently have questions at cornerback and in their return game, so Jackson could ultimately factor in their plans.
The 26-year-old was suspended twice for violating the league's policy on performance-enhancing drugs. He played 18 games with the Ravens over parts of four seasons, and he started six games at cornerback in 2014.
He was released by the team in September 2015 and claimed off waivers by the New York Giants. He lasted just two days with the Giants before Jackson was waived and wound up back on the Ravens' practice squad. Jackson ultimately was promoted to the Ravens' active roster, but an ankle injury led to him being waived with an injury settlement in November 2015.
