Prior to the 2017 season, Reed was named to the Chuck Bednarik Award watch list, the Jim Thorpe Award watch list and the Bronko Nagurski Award watch list. In 11 games (he missed the last two regular season games due to injury, but played in the Cactus Bowl) in 2017 he made 47 total tackles along with four interceptions, nine pass deflections and one forced fumble along with returning 17 kickoffs for 253 yards and one touchdown.[5] After the conclusion of the season, he was named to the 2017 All-Big 12 Conference football team.[6] Reed declared for the 2018 NFL draft on December 31, 2017.[7]
Reed was drafted by the San Francisco 49ers in the fifth round (142nd overall) of the 2018 NFL Draft.[10] In his second season, Reed reached Super Bowl LIV, but the 49ers lost 31–20 to the Kansas City Chiefs.

Reed recorded his first career interception during a 37–27 Week 8 win against the 49ers.[16] He recorded a second interception in a 20–15 Week 15 victory against the Washington Football Team.
