36 Kevin Youkilis, 3B

Yankees third baseman Kevin Youkilis will have surgery for a herniated disc in his back, and will miss 10 to 12 weeks, according to the Wall Street Journal.

Youkilis has not played since June 13, and was initially placed on the disabled list with a lumbar strain. He is hitting .219/.305/.343 in 105 at-bats. He'll have surgery Thursday.

Yankees general manager Brian Cashman expressed concern Monday when talking about Kevin Youkilis' back injury.

"Back issues usually don’t get better," Cashman said, per The Journal News. 

Youkilis has been sidelined for all but 28 games this season because of his back injury. Cashman added the Yankees went ahead and signed Youkilis this offseason because he passed his physical with flying colors and "comfort level knowing the White Sox offered him a two-year deal and that’s where he just came from."

The Yankees announced Friday that third baseman Kevin Youkilis has been placed on the 15-day disabled list with a lumbar strain.

Youkilis, who has hit .219/.305/.343 with two home runs in 105 at-bats, missed 30 games with back issues earlier this season, returning May 31. He played 11 of his team's 13 games before returning to the disabled list this time around.

Yankees third baseman Kevin Youkilis (back) returned after missing one game Tuesday during a loss at Oakland.

Youkilis' back issue was never considered serious and he had no issues during the game. Batting fifth, Youkilis went 1 for 4 with a single and is batting .240.

Youkilis has seen a drop in average since coming off the disabled list in late May and the back issue is likely not helping.

Yankees third baseman Kevin Youkilis (back) was back in the lineup Tuesday at Oakland. Youkilis took Sunday off with a stiff back and also didn't play on Monday's scheduled off day. 

Youkilis has played seven games in June and has gone 4 for 24 (.167) with no RBI and seven strikeouts.
