The Boston Red Sox may place Clay Buchholz on the disabled list with ongoing discomfort in the trapezius muscle in his neck area.

The status of Buchholz's next start has been up in the air for some time.

Buchholz last started on June 8 against the Angels, and has made just two starts, totaling 11 2/3 innings, since May 22. He is 9-0 with a league-leading 1.71 ERA.

"He's not at a point physically where he feels like he can get on the mound tomorrow without the potential of setback and not irritate the trapezius muscle," John Farrell said. "The AC joint has cleared up. There's nothing there. It's more the trapezius muscle up in the neck that is restricting him from greater intensity.

"The bottom line is ... we're not going to put him out there without making sure he's in a safe place physically."
