The Denver Broncos were delayed in their return trip to their hotel after practice in the Bay Area on Monday when the team buses were involved in what the team said was a minor accident.
"No injuries were sustained and team is back at hotel," the Broncos said in a statement.
The accident occurred in the southbound lanes of U.S. Route 101. According to the California Highway Patrol, a CHP officer who was involved in the incident was taken to a hospital with minor injuries. The CHP did not say how the officer was injured.
The CHP also said that one bus was disabled and had to be towed, and that the Broncos personnel on that bus were transferred to other buses.
"I was on my cellphone, and the next thing you know I saw guys just jumping up, 'Whoa! Whoa! Whoa! Whoa!' and I look up and the bus was swerving," tight end Vernon Davis said. "We kind of ran into the back of a bus, and a bus ran into the back of us. No one really got injured or anything. All went well.
"I think the only thing that happened was my cellphone fell out of my hand."
Monday's practice was a walk-through at Stanford in Palo Alto, California, six days before Denver faces the Carolina Panthers in Super Bowl 50.
The Broncos' team hotel is in Santa Clara, about 30 minutes south of Stanford.
DeMarcus Ware tweeted a photo from the scene. It was unclear Monday how the accident happened or what other vehicles, if any, where involved.
Later Monday, at what used to be known as media day, Ware said the accident was a scary situation.
"It was," he said. "When you think about going and doing the media, you wouldn't think about being in an accident and coming here to talk about it. But I am just glad everybody is OK from it."
