That unfortunately didn't happen.
Beckett skipped the session and is in serious jeopardy of not making his next start. The right-hander might be able to throw a bullpen session on Friday, but if he can't it's possible he'll be seeing some time on the disabled list, according to ESPN.com.
"He's not throwing today and I'd say it's questionable for him to throw tomorrow, which would then make it questionable that he would make his next start, which means he won't make it, more than likely," Valentine said Thursday.
The Red Sox obviously need all hands on deck, as they chase the New York Yankees in the AL East and a host of teams in the wild card race.
Currently, Beckett is still slated to start on Sunday against the Minnesota Twins in the series finale.
