Jackson was originally signed by the 49ers on August 8 and then released on September 2 during the team's 53-man roster cut-down before being signed to the practice squad. He was promoted to the active roster on September 16.
In four games this season, Jackson registered one defensive tackle and had three more on special teams.
Jackson entered the NFL as a fifth-round draft pick out of Cal Poly by the Baltimore Ravens in 2012. He was part of the Ravens team that beat the 49ers in Super Bowl XLVII. Jackson was released by Baltimore in September of 2015 and then re-signed to its practice squad before being added to the active roster in October of 2015.
A month later, Jackson was waived by Baltimore following an ankle injury. He bounced between the Cincinnati Bengals and Arizona Cardinals before, once again, landing with Baltimore in October of 2016, where he spent time between the practice squad and the active roster.
In December of 2016, Jackson was signed by the Detroit Lions off of Baltimore's practice squad and then later placed on injured reserve with an ankle injury.
Over his five-year NFL career, Jackson has 38 combined tackles, eight assists, and four passes defensed, according to NFL.com. He has appeared in 26 career games with eight starts. Six of those starts occurred in Baltimore and two last season with Detroit.
