Atlanta Braves third baseman Chipper Jones announced on Thursday that he’d retire from baseball at the end of the 2012 season. This gave him the opportunity to have a farewell tour, and perhaps reach some further statistical milestones on the way to induction in the Hall of Fame.

Just two days later, there’s a detour:

Chipper has torn meniscus in his left knee.He will have surgery on Monday.He hopes to return for the home opener.

And what’s even stranger is how this happened:

Chipper hurt the knee while running in the outfield just before Thursday’s retirement press conference

Jones has had knee troubles before; they limited his play to 126 games in 2011 and 95 games in 2010. He’ll have three weeks to recover before Atlanta’s home opener against the Brewers on Friday, April 13.
