Begelton, 27, wound up going undrafted out of Lamar back in 2016. He later signed on with the Calgary Stampeders of the CFL in 2017.
The Packers signed Begelton to a futures contract this past January.
During his three seasons with Calgary, Begelton caught 149 passes for 2,236 yards receiving and 12 touchdowns over the course of 33 games. He also rushed for 38 yards and a touchdown.
Winn, 31, is a former sixth-round pick of the Browns back in 2012 out of Boise State. He signed a four-year rookie deal through the 2015 season.
At the start of 2015, Winn was traded by the Browns to the Colts for a conditional seventh-round pick. From there, he signed on with the Broncos the following year and returned to Denver in 2019 on a one-year deal.
The Broncos placed Winn on injured reserve last year with a triceps injury and opted to cut him loose this past March.
In 2020, Winn has appeared in one game for the Packers and recorded a pass defense.
