Lackey will start Sunday against the Pirates after his scheduled start Saturday was rained out, MLB.com's Carrie Muskat reports.
Analysis:
The Cubs will push Lackey back a day, as expected, while taking the off day as an opportunity to push Kyle Hendricks back a series and pitch Jason Hammel, Jake Arrieta and Jon Lester against the division-rival Pirates next week. Lackey will face Julio Teheran in Sunday's game and remains a strong play in all formats.
