Mark Teixeira was forced to leave Thursday game with a bruised right knee.
"It couldn't have gotten me in a worse spot," Teixeira said.
Teixeira said Alfredo Aceves' 74-MPH curveball hit him in the side of the knee.
"It got bone, ligaments, it got it all," Teixeira said.
Teixeira said he was worried, but he doesn't think, at this point, he needs further tests. He didn't rule out playing Friday at home against Toronto.
