An MRI has revealed a Grade 1 strain and Teixeira believes he'll miss one to two weeks, reports Sweeny Murti of WFAN.
Teixeira, 32, is hitting .255/.335/.478 with 23 homers, 81 RBI and 65 runs this season.
With Teixeira out, the Yankees have several options at first base. Newly-acquired Steve Pearce is an option. Nick Swisher could play first with Ichiro Suzuki sliding to right field while either Andruw Jones or Raul Ibanez plays left. Casey McGehee could also fill in, as could Eric Chavez, with Jayson Nix playing third. The best guess is they play matchups instead of sticking with one specific lineup until Teixeira returns.
