Teixeira was held out of the Yankees' lineup on Sunday, one day after he was a game-time scratch with left wrist tendinitis. Yankees manager Joe Girardi originally said he intended to play Teixeira at first base in the series finale against the Royals, but he reconsidered.
"He's still sore, so I didn't see any reason to play him today," Girardi said. "He's just day-to-day. Tendinitis sometimes takes some time to get out, so he's got to work out that soreness. The diagnosis was good, but you never know how long it takes to get it out."
Teixeira was examined by specialists at Kauffman Stadium on Saturday, undergoing strength tests but no X-rays, and he was advised not to swing a bat for a day to help alleviate the soreness.
He believes the injury occurred on Wednesday in Baltimore, and he said it only affects him when batting right-handed.
"I'm just going to rest," Teixeira said. "I have this little splint, so it's not moving. I'm not going to go out and take grounders or take [batting practice] or anything. I'm just getting a full day's rest."
With Teixeira out of the lineup, Nick Swisher made his second consecutive start at first base for New York. Teixeira said that he did not expect to be available to pinch-hit against Kansas City, giving him a full day off.
"They said it's going to be a day or a couple of days, but we've just got to get it out," Teixeira said. "We're in a stretch [of the schedule] right now where we don't get any breaks. It's better to have one or two days now than two or three weeks."
After Sunday's game, Girardi said that he did not expect to play Teixeira in New York's starting lineup on Monday either, with the Rays starting left-hander Scott Kazmir. Girardi said that Teixeira could be a player off the bench.
"If I'm not able to start him, I hope he's available to pinch-hit," Girardi said.
