Teammates voted him in as a captain ahead of the 2020 season.
The change comes after the quarterback was photographed at an event without a mask following Sunday's game while breaching COVID-19 protocols:

Dwayne Haskins was finally back as a starter [due to injury] and after losing to the #Seahawks, apparently decided to party at a strip club. The team is aware of the posts and are in contact with the league while handling it internally, per @NickiJhabvala https://t.co/z5uYHTQJ19
Haskins said Wednesday he was not at a strip club as initially reported, but that he still "deserved" the punishment for not wearing his mask in a public setting of more than 10 people, per Nicki Jhabvala of the Washington Post.
Washington said it would handle the matter internally, per Tom Pelissero of NFL Network.
Despite the loss of the captaincy, Haskins continues to take first-team reps, according to Jhabvala.
The 2019 first-round pick began the season as the starter, but Rivera benched him after a 1-3 start.
Injuries to Kyle Allen (ankle) and Alex Smith (calf) pushed Haskins back on the field, as he started in Sunday's 20-15 loss to the Seattle Seahawks. He totaled 295 passing yards and a touchdown but also threw two interceptions.
It appears he will remain under center for the team's Week 16 battle against the Carolina Panthers. At 6-8, Washington leads the NFC East and can clinch the division Sunday with a win and New York Giants loss.
