Disgruntled with the situation, it became clear that Volek would be headed out of town, despite a no-trade clause in his contract.
"We're excited to add Billy Volek to strengthen our quarterback position," said General Manager A.J. Smith. "We're always exploring ways to upgrade the talent on the Chargers. Billy brings talent and experience, and adds depth at that very critical position."
The Kansas City Chiefs had also been interested in Volek's services.
Volek is expected to land at number two on the depth chart behind starter Philip Rivers. He has started ten games, all for Tennessee, over a career that began in 2000. He is 312-of-517 for 3,505 yards with 26 touchdowns and 13 interceptions over his career.
The acquisition of Volek comes during the Chargers bye week, giving him close to two weeks to learn the offense before the Bolts play Baltimore.
