The Bucs continue to build their offseason roster, announcing Wednesday the signing of CFL linebacker Jeff Knox, who was with the team last year before he was among their final cuts.
Knox, 25, had three tackles in the preseason with Tampa Bay last season. He returned to the CFL and had 30 tackles in eight games with the Saskatchewan RoughRiders. He led the CFL with 122 total tackles in 2015 as a rookie out of California (Pa.).
The Bucs have their top three linebacker jobs all but locked up for 2018 in Lavonte David, Kwon Alexander and Kendell Beckwith, but Knox has a shot at a backup job. Adarius Glanton, who played well as the top backup last season, is a restricted free agent and is coming off a fractured lower leg suffered in the season finale; the Bucs also promoted rookies Riley Bullough and USF's Nigel Harris from the practice squad at the end of 2017.
NFL teams have rosters expand to 90 players in the offseason, but will add free agents and draft picks and then must cut the roster back to 53 in September for the start of the 2018 season.
