He will be replaced by non-roster right-hander Tim Redding, who already was on the list of scheduled pitchers for the game and now will draw the start.
Lilly is one of at least two Dodgers players whose schedules have been affected by illness this spring. First baseman/outfielder Jay Gibbons has been out for several days and still hadn't played in a Cactus League game before Wednesday. He served as designated hitter against the Royals. He'll be the DH Thursday and then ease into the outfield mix.
It wasn't immediately clear when Lilly will make his first start or to what degree his illness will throw off the pitching schedule for the Dodgers, who have their five starters lined up in the same way they plan to align them when the season starts.
Lilly, 35, won each of his first five starts for the Dodgers after they acquired him from the Chicago Cubs at last year's trading deadline before going 2-4 the rest of the way, finishing the season a combined 10-12 with a 3.62 ERA. He re-signed with the Dodgers last winter, accepting a three-year, $33 million contract.
