Jackson played in just eight games last season and recorded three sacks — all of which came in Week 1 against the Steelers. The former second-round pick was placed on injured reserve following knee surgery in mid-November. In 23 career games, Jackson has totaled 21 tackles and six sacks, along with five TFLs. ESPN’s Adam Schefter said Jackson is out through the duration of training camp “at a minimum,” suggesting his absence could stretch into the regular season. This is presumably the same knee injury that ended Jackson’s campaign last year.
