Asa Rashaan Webster Jackson (born December 2, 1989) is an American football cornerback and return specialist for the Baltimore Ravens of the National Football League (NFL). Jackson was born in Sacramento, California and attended Christian Brothers High School. He excelled while playing college football for Cal Poly.
Jackson was a four-year starter at California Polytechnic State University, San Luis Obispo, more commonly referred to as Cal Poly. He finished his college career with 137 solo tackles, 199 total tackles, 8 interceptions for 307 yards (ranks first in school history) and 3 touchdowns (ties school record with David Fullerton), 40 pass deflections, 3 forced fumbles, and a single sack for -6 yards. He played in 43 games, and started in 42 of them.
Jackson was selected in the 5th round, 169 overall pick in the 2012 NFL Draft. He is probably most known for returning a punt for a touchdown against the Atlanta Falcons during a preseason NFL game, and then started doing the famous Gangnam Style dance. Although, the play was nullified by a holding penalty. Jackson was placed on injured reserve on December 16, 2014. Jackson was cut by the Baltimore Ravens on September 5, 2015.
Jackson was suspended for four games without pay for violating the NFL policy on performance-enhancing substances on December 11, 2012, for using Adderall, a prescription drug, to treat his attention-deficit hyperactivity disorder.  On August 2, 2013, he again violated the PED policy and was suspended without pay for an additional 8 games of the 2013 season. Asa Jackson has now completed the required paperwork and has been authorized to take Adderall.
