Clay Buchholz was scheduled to start on Sunday, but he will not make the start due to illness.
Even though Buchholz struggled in his last start, he has been strong for the team with a 4-0 record and a 2.53 ERA and 31 strikeouts over his last five starts.
It is unclear who will start in place for Buchholz at this time, but Aaron Cook has been told he will not make his start tonight for Pawtucket. Cook has not appeared for the Red Sox since May 5 when he suffered a laceration on his right knee.
