ET: Buehler is sick, according to Rob Bradford of WEEI in Boston. He will pitch in a minor league game on Monday. 9:15 a.m. ET: The Boston Red Sox scratched free agent acquisition Walker Buehler from his start on Sunday in what would have been his final tune-up before the regular season.

FORT MYERS, Fla. — That Cooper Criswell, not Walker Buehler, pitched the Grapefruit League finale for the Red Sox on Sunday, was a bit of an alarming development early Sunday. But it turns out Buehler, like many of his teammates this spring, is dealing with a stomach bug.

Boston Red Sox starting pitcher Walker Buehler (illness) is scheduled to take the mound against the Texas Rangers on Saturday. The right-hander was scratched from his most recent start due to a minor illness.
