Mark Teixeira has inflammation in his left wrist but suffered no structural damage, an MRI revealed Tuesday.
The Yankees first baseman received a cortisone shot and will be re-evaluated Friday.
"Best case, I'd love to be able to get here early on Friday and swing a bat and be able to tell Joe [Girardi] I can play," said Teixeira, who spoke to reporters before Tuesday night's game and wore a brace on the injured wrist. "We're gonna take it easy the next couple days, treat it, and then we'll see where we are on Friday."
Teixeira first injured the wrist last Sunday while swinging at a pitch from Red Sox lefty Felix Doubront. He aggravated it Monday, diving for a ground ball against the Orioles in the seventh inning, and was forced to leave the game.
Girardi said it was a "huge relief" to hear that Teixeira suffered only inflammation. "In the back of my mind," the manager admitted, "I was fearing the worst . . . For Tex to come out, I know it has to be very painful."
Teixeira said he wanted to play through the pain, but it "wouldn't hold up" and would have even affected his fielding.
Nick Swisher started at first base and batted cleanup in Teixeira's place.
Teixeira, 32, said he dealt with a similar injury in 2009, which also was caused by an awkward swing."I know when something is hurting and sore and I know when something is seriously injured," he said. "I didn't feel like I was seriously injured."
The time off disrupts what had been Teixeira's most productive stretch. He hit .298 with a .386 on-base percentage, seven homers and 27 RBIs in July.
"But we're not Supermen," Teixeira said. "Everyone has to deal with things and it's better to deal with it now."
