The Eagles waived Bello on Wednesday.
Philadelphia called Bello up from the practice squad late last season, with the reserve linebacker suiting up in three contests and registering one tackle. The team apparently deemed him an expendable piece heading into training camp and signed safety Trae Elston to take Bello's spot on the offseason roster.
Bello was promoted to the Eagles' 53-man roster Friday, Adam Caplan of SiriusXM Radio reports.
Bello totaled six tackles in 16 games as a rookie with the Browns last season but he's been on the Eagles' practice squad in 2018. The 24-year-old brings added depth to the linebacking corps with Jordan Hicks still nursing his calf injury.
