Worley (3-2, 3.07 ERA) was expected to start against Matt Garza on Wednesday at Wrigley Field. The Phillies have not yet decided if Worley will need to go on the disabled list. However, it appears Philadelphia anticipated that Worley might need a DL stint as Joe Savery will be on the two-game road trip with the team to Chicago. Savery has appeared in eight games for the Phillies in 2012 and has a 4.50 ERA in eight innings of work.
The bad news comes after Tuesday's 4-3 10-inning win over the Houston Astros and the Phillies' first three-game win streak of the 2012 season.
