More than a week after becoming infamous for an attack that left two with injuries, Callis, 24, surrendered to police and was taken into custody for multiple assault charges, investigators say in connection to the unprovoked attack of two 23-year-olds.
The Ravens topped the Commanders 30-23 in a hotly contested game, but it was the fireworks after the game that went viral after Callis, sporting a Lamar Jackson jersey, took out a pair of fans wearing red and crimson Commanders' gear.
An Instagram video posted by a user that was picked up by multiple outlets went viral showing Callis accosting the opposing fans outside an area bar.
The person shooting the video can be seen shouting "DO WE HAVE A STRAGGLER?" as the pair approached two people wearing Commanders' jerseys and goading them.
In the video, which has now been viewed millions of times, Callis can be seen kicking one person before throwing a right hook that knocked him out, then tossing another to the ground.
Much to the crowd's delight, the man then flexed while shouting "I don't lose."
The cameraman and Callis then high-fived.
Following the release of the video, there has been a massive fallout, which began when Callis reportedly lost his job after the Internet swiftly identified him.
"(We have) a zero-tolerance policy for violence and aggressive behavior," insurance firm Maury Donnelly & Parr posted on social media once Callis was identified. "This individual is no longer employed with our firm."
Now, on top of that, Callis is charged with first-degree aggravated assault and three counts of second-degree assault.
