Eiland's fall occurred in the sixth inning while the Angels were batting, shortly after Ivan Rodriguez and Torii Hunter were both ejected following a benches-clearing incident. Eiland was examined by Angels team physician Craig Milhouse and the Yankees announced that he was up and around.
Yankees manager Joe Girardi said that Eiland, 42, has been fighting a cold and was on medication. He had worked out strenuously on Monday morning and had not eaten since lunch, according to Girardi.
Later in the game, bullpen coach Mike Harkey made a mound visit with Eiland resting in the clubhouse. Eiland did not speak to reporters.
He is in his first season as the Yankees' pitching coach after helping to develop young pitching in New York's Minor League system. Eiland had a 12-year Major League career, appearing with the Yankees, Padres and Rays from 1988 through 2000.
