Atlanta Braves third baseman Chipper Jones was placed on the 15-day disabled list and the team purchased the contract of catcher J.C. Boscan from Triple-A Gwinnett on Saturday.
The Jones move is retroactive to May 24 as he is suffering from a left calf contusion that he sustained in a May 18 game against Tampa Bay.
In that game, B.J. Upton stung a hard one-hop infield single off Jones' leg in the third inning, which caused the 40-year-old to leave the game after the seventh.
Jones walked as a pinch-hitter Wednesday against Cincinnati, but hasn't played since.
In 29 games this season, Jones is hitting .307 with five homers and 24 RBI. He plans to retire after the season.
The Braves are 19-5 with Jones in the starting lineup this season, but 7-16 without him.
Boscan has appeared in five games over the past two seasons with the Braves and has three hits in nine at-bats.
He will start Saturday's game against Washington as backup catcher David Ross left Friday's game with a right groin strain.
Regular catcher Brian McCann played the rest of Friday's game after Ross left, but he had missed the previous three games with flu-like symptoms.
