The 24-year-old Jenkins started six games last season, including four straight early in the season when a knee injury sidelined starting nose tackle Grady Jackson. He also started the eighth game of the season against Washington and the season finale at Chicago.
After playing in NFL Europe in the spring, the undersized but quick Jenkins made the team primarily on the pass-rushing ability he flashed during practice and preseason. After going without a sack during the first six games, Jenkins got a half of a sack in the seventh game against Dallas then solo sacks in consecutive games against Washington and Minnesota. He also recorded a sack at Philadelphia and another in the finale at Chicago.
Along with his 4 1/2 sacks, Jenkins tallied 28 tackles, 18 of which were solo, one fumble recovery, one forced fumble and two passes defensed.
Jenkins originally signed with the Packers as an undrafted free agent but failed to make the 2003 final roster. He was re-signed after the season.
Exclusive-rights free agents are players with less than three years of NFL experience. They are not allowed to negotiate with another team. Jenkins was one of three such players on the Packers' roster; the others being cornerback Jason Horton and tight end Ben Steele. The Packers have not signed either of those players.
