Kevin Youkilis puts off surgery

BOSTON -- Boston Red Sox third baseman Kevin Youkilis returned to the lineup Tuesday night, but he said that he will have offseason surgery to repair a sports hernia he's been dealing with.

"It's an easier procedure and a lot of guys have had it done," he said before going 0-for-3 with a strikeout in the Red Sox's 18-6 win.

While Youkilis was in against Toronto on Tuesday, designated hitter David Ortiz was a late scratch from the Red Sox's lineup because of back spasms. Ortiz, who showed no ill effects prior to the game but did take an awkward swing in the cage during batting practice, was replaced by Jed Lowrie in the cleanup spot. Lowrie went 0-for-4 with two strikeouts.

"Right before the game, and I mean right before the game, his back was getting stiff," Red Sox manager Terry Francona said of Ortiz. "He thought he was going to be OK, we turned in the lineup cards, but then he tried to swing and it got really tight, so we had to scratch him."

This is the second time Youkilis has had this type of injury. The first was during the 2006 season, so he figures he'll be able to play through the discomfort until the season is over.

"The bottom line for me is going out there and playing through it," he said. "There are a lot of guys banged up here. It's September and there are a lot of guys feeling stuff."

Youkilis recently received an injection in his hip because of bursitis, and he's also dealt with a sore back this season. His hip has been inflamed for a while and has not healed.

"We're going to attack it and go day by day and play as I can tolerate it," he said. "Hopefully that's every day and all nine innings."

Also, Red Sox manager Terry Francona said pitcher Bobby Jenks has been diagnosed with a pulmonary embolism in his back.

Boston also summoned pitchers Trever Miller and Junichi Tazawa, speedy outfielder Joey Gathright, shortstop Jose Iglesias and first baseman Lars Anderson from the minors. Outfielder J.D. Drew was transferred from the 15-day disabled list to the 60-day DL and outfielder Nate Spears was designated for assignment.

Doctors found the embolism, which occurs when the main artery of the lung or one of its branches becomes blocked, during the course of all the testing Jenks had on his ailing back.

"Bobby's doing fine, and he's on the proper medication. He's doing great," Francona said.
