BOSTON -- Right fielder J.D. Drew was out of the Red Sox's lineup Sunday afternoon, the second successive game he has missed after receiving a cortisone shot in his left shoulder after Friday night's game.

"He's doing OK," Sox manager Terry Francona said before Sunday's matinee rubber game against the Rangers at Fenway Park. "With the day off [Monday], we'll try to stay away from him today and that gives him three [days off]. [That] should get him back to feeling pretty good. That's the idea."

Drew, who was replaced in the lineup by Mark Kotsay, was confident he would return to the lineup Tuesday against the Yankees.

"I completely expect to be right back in the lineup," said Drew, who added he felt the pain in the collarbone area and worked its way down his left arm. "It's kind of hard to explain. We don't really know, more of kind of like a tennis elbow thing, where it kind of wears on you after a while.

"From what the doc and everybody tells me, it can be caused by just a bone injury like a dive or something. But this just kind of started minor and grew into a like really strong. I don't know if it's tendinitis or what it is in that joint.

"So cortisone's a great option for that area," Drew added. "It's not really an area that you have to be concerned with putting cortisone in. So hopefully, after all the soreness just from the injection itself, because I was pretty sore and stiff [Saturday] and then [Sunday], I feel a little better. So hopefully by Tuesday it's nonexistent."

Drew, who is hitting .261 with eight home runs and 27 RBIs and went 2-for-3 with two walks and a stolen base Friday before the cortisone injection, said the problem was not caused by a particular injury, but had been wearing on him for a while.

"It's hard to say," he said. "I've felt it a little bit maybe off and on in Spring Training. I've had it throughout my career. It usually just goes away but this one kind of lingered and over about the last two-and-a-half, three weeks, it'd gotten pretty severe."

There is a clause in Drew's contract with the Red Sox, of which he is in the third of five years, allowing the team to opt out of either of the last two seasons if Drew spends 35 days on the disabled list in either 2009 or '10 with an injury related to his pre-existing right shoulder condition, or he finishes 2009 or '10 season on the disabled list and cannot play the outfield the following season. This current problem, in his left shoulder, would not impact that pre-existing clause.

Kotsay, who was activated from the disabled list before Tuesday's game, made his season debut Wednesday, going 0-for-1 after replacing Drew in right field in the eighth inning. Kotsay then moved to first base when Kevin Youkilis left with an ankle injury. Sunday marked Kotsay's first start of the season, and he hit his first home run of the year, a solo shot to right in the fourth off Texas' Vicente Padilla.

"Obviously, it's new," Kotsay said of making his first start. "But get my feet wet today and hopefully it'll take some of the anxiousness away and then as the game gets going I'll settle down.

"You get anxious any time you haven't played in a while. I've come into a couple games and it's little different than going out there for the first pitch. So, I'm excited."

Kotsay is still adjusting to life off the bench.

"It's difficult," he said. "You have to prepare yourself mentally, and stay focused on the game which is easy. But at the same point, you're not really in the flow of the game and you get thrown in. It's just a mentally that is learned and fortunately I've witnessed enough guys doing it in my career that I've got some experience with some older guys and learned how to do it.

"I watched Lenny Harris in the National League, one of the best pinch-hitters. Mark Sweeney is another good friend that I've watched and talked to. When I broke in, [I watched] Jim Eisenreich, John Cangelosi. Those are four of the best that did it at the end of their careers and did it quite well."
