"We'll have an MRI to get a more clear diagnosis, but we think it's probably going to be a DL situation," manager Aaron Boone told reporters after the game, calling it a groin or hip adductor injury.
The Yankees catcher, who has 14 home runs and 41 RBIs but is hitting just .190 this season after going 0-for-4 on Sunday, was hurt when he tried unsuccessfully to beat the throw to first on his double-play grounder in the 10th inning.
The Yankees have only one other catcher on the 40-man roster -- Kyle Higashioka, who is at Triple-A Scranton/Wilkes-Barre -- making him the likely roster replacement, Boone said.
Higashioka has 20 career big league plate appearances, having been in nine games for the Yankees last season. He was hitless in 18 at-bats, with two walks.
At Scranton/Wilkes-Barre this season, he is hitting .191 with five home runs and 22 RBIs in 51 games.
Last season, Sanchez slugged 33 home runs and drove in 90 runs while hitting .278.
