Bergman will have his start pushed back to Saturday when the Rockies take on the Cubs, Thomas Harding of MLB.com reports.
Manager Walt Weiss is shuffling his rotation a bit this week, moving Jorge De La Rosa up to start Thursday's game against the Giants while Bergman will take the ball for Saturday's game at Wrigley Field. Saturday marks Bergman's first start of the season after being used as more of a long reliever to begin the year. In four starts last season, Bergman struggled his way to a 6.89 ERA over 15.2 innings of work.
