"I was a little dizzy and had a headache, which is why [trainer Kevin Rand] took me out," said Avila, who missed time last season with delayed concussion symptoms. "I was out of sorts for a little while when I got to the bench, but once they laid me down and iced me up, I felt a lot better."
The former American League All-Star was examined by Rand and Tigers manager Brad Ausmus before walking off the field. Bryan Holaday replaced him behind the plate.
Avila took an indirect foul ball to the mask earlier in the game, which he said "got me a little bit, but nothing like the second one."
"I actually feel OK now," he said. "I'll be back out there as soon as I can."
Ausmus said he plans on giving Avila the day off Wednesday, preferring to err on the side of caution with his starting backstop.
"I didn't like the way he was answering the questions that Kevin asked him right after he got hit," Ausmus said. "But Alex said he feels fine and he came through all the concussion tests with flying colors, so I don't think there is too much to be concerned about."
