Bush, 33, was playing in his tenth NFL season when he suffered a meniscus tear after returning a punt against the Rams while playing for the San Francisco 49ers at the Edward Jones Dome. Bush landed awkwardly after slipping on concrete and was ruled out for the remainder of the season.
The Rams were ordered to pay $4.95 million in compensatory damages and $7.5 million in punitive damages. Bush previously sued public agencies associated with the dome, but those cases were dismissed last week.
Bush filed the suit in 2016. He referred to the surface surrounding the field at the time as the "concrete ring of death."
Bush works as an analyst for NFL Network. He posted a GIF on Twitter of a man smiling after news of the verdict broke.
