John William Volek (born April 28, 1976) is an American football quarterback for the San Diego Chargers of the National Football League. He was originally signed by the Tennessee Titans as an undrafted free agent in 2000. He played college football at Fresno State.
Volek attended Clovis West High School in Fresno, California, and was a letterman in football. In football, as a senior, he was named the Northwest Yosemite League Offensive Player of the Year. He then went to California State University, Fresno, where he led the Bulldogs to a Western Athletic Conference title in 1999 and set the NCAA record for career lowest percentage of passes intercepted.
Volek was signed by the Tennessee Titans in 2000 from free agency, after not being selected by any team in the 2000 NFL Draft. He would see very little action during his rookie season, completing 0 of his 3 passes with no touchdowns and no interceptions. After such a small amount of play time, he would not be seen on the field again until the 2003 season, where he would make a name for himself as one of the National Football League's more talented backup quarterbacks.
