CLEVELAND (AP) -- New York Yankees closer Mariano Rivera was not available for Monday night's 6-3 loss to the Cleveland Indians because of a sore right triceps muscle.
Yankees manager Joe Girardi revealed Rivera's condition following the game. He said Rivera told him before the game that he was sore after blowing a save on Sunday against the Mets.
Girardi said there are no current plans for Rivera to undergo medical tests.
Rivera said he's not "concerned at all" and hopes to be able to pitch Tuesday. Girardi said he would have used right-hander David Robertson had there been a save situation in the series opener against the Indians.
The 41-year-old Rivera is 1-1 with 21 saves in 25 chances and a 1.91 ERA in 35 appearances.
