Rookie kicker Rob Bironas of Georgia Southern was placed on waivers to make room on the roster.
Jackson, a 6-2, 204-pound Washington State product, was signed by the Seattle Seahawks as a free agent on April 28, 1998, and spent the majority of the '98 and '99 seasons on the Seahawks' practice squad. Waived September 6, 1999, he signed with Tennessee and played in one game - vs. Pittsburgh October 5 - before suffering a back injury and being placed on injured reserve December 1. He subsequently was released March 1, 2001, and had not been on an NFL roster in the interim.
Jackson played for the Los Angeles Avengers of the Arena Football League in 2000 and earned AFL 'Rookie of the Year' honors.
Earlier, Jackson had been one of quarterback Ryan Leaf's primary targets at Washington State, where he set the Cougar single-season record for touchdown receptions with 11 in 1997.
The newcomer has been assigned jersey number 7.
