Jones, 38, was injured in the sixth inning of Tuesday's game while making a defensive play. The Braves said Thursday an MRI indicted a tear of the anterior cruciate ligament in Jones's left leg.
The injury requires surgery, but a date for the procedure hasn't been announced. Recovery is expected to take at least six months. The injury could signal the end of Jones's career as he has hinted that this season -- his 17th in the major league -- may be his last as a player.
Jones is hitting .265 with 10 home runs and 46 runs batted in 95 games this year. He is a six-time All-Star and was voted the National League Most Valuable Player in 1999. Jones is a career .306 hitter with 436 home runs and 1,491 RBI. He's played his entire career with the Braves.
