Minnesota Twins prospect Byron Buxton was taken off the field in an ambulance after an outfield collision in his first game for Double-A New Britain on Wednesday night.

The 20-year-old center fielder sustained a concussion when he crashed into right fielder Mike Kvasnicka diving for a ball Kvasnicka caught in the fifth inning. The collision delayed play for more than 30 minutes.

Twins general manager Terry Ryan was at the game and rode in the ambulance with Buxton and Kvasnicka, who walked away after the collision. Ryan said Buxton was unconscious for 10 minutes.

"He's alert," Ryan said. "He has a concussion, so we'll have to take the normal procedures and protocol for concussion symptoms. He'll certainly be watched. ... It could have been a lot worse. We are grateful for just the concussion. That was very scary."

Buxton was the second overall pick in 2012.
