The Browns waived Gillan after removing him from the reserve/COVID-19 list Wednesday, Jake Trotter of ESPN.com reports.
Gillan landed on the reserve/COVID-19 list ahead of Week 14 and was sidelined for two games. The Browns signed Dustin Colquitt to fill in at punter during Gillan's absence, but in the process, Colquitt won the starting kicking job. Gillan averaged 46.2 yards per punt as a rookie, but he has seen his averages drop in each of the past two seasons.
