The Denver Broncos are back at their hotel in Santa Clara after their buses were involved in a minor accident following their practice at Stanford Stadium.
Team spokesman Patrick Smyth says nobody was injured.
Outside linebacker DeMarcus Ware tweeted a photo of players standing alongside their bus. He posted: "To keep the day interesting, we have a small wreck. Looks like everyone is ok though."
The Broncos and Carolina Panthers, who meet in Super Bowl 50, make their first public appearances at media day on Monday night.
