Lewis Cine had surgery in England on Tuesday to repair a compound fracture in his left leg.
The rookie safety was injured while blocking during a punt return in the Vikings' 28-25 victory over the Saints at Tottenham Hotspur Stadium on Sunday.
The "successful surgery" was performed by Dr. Ash Vasireddy at Cleveland Clinic London, according to a team statement.
Cine was a first-rounder, the 32nd overall pick, in the 2022 draft out of Georgia. A member of the Vikings medical staff remains with Cine, who will go on injured reserve, until he is able to return to Minnesota.
