SANTA CLARA, Calif. (AP) — The Denver Broncos worked out Monday as they prepare for Super Bowl 50, but they saved their hardest hits for after practice.

The Broncos' 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 are in San Jose attending media night, now dubbed Super Bowl Opening Night by the NFL. The league moved the supersized press conference to Monday night from its usual Tuesday daytime slot to give more fans a chance to watch live on cable.

Broncos quarterback Peyton Manning was asked if he would retire after the game. Manning said, he hadn't made up his mind and didn't see himself knowing that until after the season is over.

Panthers linebacker Thomas Davis returned to practice on Monday with no limitations. Davis broke an arm in the NFC championship game but says he expects to play in the Super Bowl.
