The San Francisco 49ers have promoted cornerback Asa Jackson to the team’s active roster from their practice squad ahead of Sunday afternoon’s game against the Seattle Seahawks. As a corresponding move, the team released cornerback Keith Reaser.
Jackson has been a practice squad warrior over the past two seasons, having first joined the 49ers first back in August. He did not make the team’s final roster but returned to the practice squad in early September.
Last season, he appeared in four games and made a pair of starts as a member of the Detroit Lions, making seven tackles and defending a pass. His season ended when he was placed on injured reserve with an ankle injury.
He first joined the league as a fifth-round pick by the Baltimore Ravens in the 2012 NFL Draft out of Cal Poly. His first four NFL seasons came with the franchise, including a 2014 season in which he made a career-high 28 tackles, along with six starts and three passes defended.
In addition to three separate stints with the Ravens, he has made practice squad appearances with the New York Giants, Cincinnati Bengals, and Arizona Cardinals, before joining San Francisco this year.
The 49ers have moved on from Reaser, after he appeared in 15 games with the team last season and made 23 tackles, while forcing a pair of fumbles. He was selected in the fifth round of the 2014 NFL Draft by the team out of Florida Atlantic and has appeared with the team since.
