New York Yankees first baseman Mark Teixeira's injured wrist may be worse than originally thought but will likely not require surgery.
Instead of missing the first month of the regular season, Teixeira might not return until June, MLB.com reported Sunday.
Teixeira was injured on March 6 and was expected to miss eight to 10 weeks with a right wrist sprain.
The injury is now diagnosed as a partially torn tendon sheath, which is similar to what cost Toronto Blue Jays slugger Jose Bautista most of the second half of last season.
"This is one of those things I can't come back too early," Teixeira told reporters Sunday. "We saw last season when I tried to play too early (with a calf injury) what happened. If I try to play too early from this we could miss the whole season, and we don't want that. I don't know if it's the beginning of May, the end of May, the beginning of June, I don't know when it is but we got a whole bunch of season left and the time that really matters is the playoffs."
Yankees general manager Brian Cashman told reporters he was surprised to hear Teixeira say the injury was to the tendon sheath and not the tendon itself.
Cashman said he called team doctor Chris Ahmad to get more details about the first baseman's injury.
"Ahmad told me if he had a fully torn sheath, it's automatic surgery, and if he had a partially torn sheath with an unstable tendon, it's automatic surgery," Cashman said. "This is a best-case scenario injury, the only one that can heal without surgery."
Teixeira, 32, hit .251 with 24 home runs and 84 RBI in 123 games in 2012. He had at least 33 home runs and 108 RBI in each of the previous three seasons.
Signing outfielder Brennan Boesch allows the Yankees to move Juan Rivera to first base in Teixeira's absence.
