Milne will make Washington's initial 53-man roster, John Keim of ESPN.com reports.
Milne was Washington's seventh-round pick out of BYU where he was Zach Wilson's top target in 2020. He caught 70 of 95 targets for 1,188 yards and eight touchdowns during his final collegiate season. The rookie will likely be the No. 7 wideout on the depth chart and will need to produce on special teams before he gets involved offensively.
