Chicago Cubs right-hander Yu Darvish experienced pain in his right triceps during a Thursday throwing session and won't be returning to the starting rotation Saturday as the club hoped. Manager Joe Maddon said a new timetable will be formulated after the team returns to Chicago. "It didn't go that well and he was not able to cut it loose," Maddon said after Darvish's workout at Dodger Stadium prior to the contest against the Los Angeles Dodgers.
