The Chargers signed Bradley as an undrafted free agent Saturday.
Listed as a wide receiver during his collegiate stops at Texas Tech, Boston College and Kansas State, the 6-foot-5, 241-pound Bradley will transition to tight end as he makes the jump to the professional ranks. As a fifth-year senior at Kansas State this past fall, Bradley started in five of his nine appearances and totaled 13 catches for 184 yards and two touchdowns on 21 targets.
