Arrighetti was pulled from his start Friday against the White Sox due to right foot nerve irritation.
Arrighetti gave up two hits and two walks and hit two batters while surrendering three runs in the first inning. He then felt discomfort on the mound while warming up for the second and left the game with a trainer. Arrighetti is lined up to take the mound again Wednesday against the Angels, though it remains unclear whether he'll be ready to go by then.
