Clay Buchholz (who bears no resemblance to the pitcher of 2013) will test his left knee today in a bullpen session at Fenway. Subsequent to the session, the team will determine whether the right-hander makes his next scheduled start. Apparently, the knee "buckled" during Buchholz's three-plus-innings stint on Monday. Red Sox manager John Farrell was candid about the situation, "We're not blind to what everyone sees. And yes, there is concern because you're talking about a guy that was on his way to potentially a Cy Young year last year and now he's only shown flashes of it, either inside a given game or for a given start." Stay tuned.
