New Orleans Saints quarterback Jameis Winston will miss Sunday's game against the Minnesota Vikings in London due to back and ankle injuries.
The Saints downgraded Winston from doubtful to out on Saturday night, London time.
Veteran Andy Dalton will serve as the starting quarterback for the Saints (1-2).
Winston has been dealing with back issues since Week 1. The injuries to his ankle and foot became known during the week following the Saints' second game.
Winston didn't practice at all this week, so Saturday's announcement wasn't an unforeseen development.
Winston, 28, has passed for 858 yards, four touchdowns and five interceptions this season in his third campaign with the Saints.
He spent his first five NFL seasons with the Tampa Bay Buccaneers. Winston has passed for 21,840 yards, 139 touchdowns and 96 interceptions in 86 games (80 starts).
The Saints ruled out receiver Michael Thomas (foot), guard Andrus Peat (concussion) and safety Marcus Maye (ribs) on Friday.
Dalton, 34, has started 148 of 152 games played during his 12 NFL seasons. He has passed for 35,279 yards, 226 touchdowns and 135 interceptions for the Cincinnati Bengals (2011-19), Dallas Cowboys (2020) and Chicago Bears (2021).
New Orleans also signed quarterback Jake Luton to the active roster from the practice squad on Saturday. Luton, 26, started three games for the Jacksonville Jaguars in 2020 and passed for 624 yards, two touchdowns and six interceptions.
The Saints also waived fullback Adam Prentice.
