Josh Beckett pitched today and seemed fine:

Beckett missed two days last week after sustaining a concussion Monday when he was hit in the head by a ball off the bat of Red Sox staff member Ino Guerrero. He pitched a simulated game on Friday, then went 3 2/3 innings Tuesday against the Houston Astros, allowing one run on a wind-blown double while striking out four.

That’s good news for Beckett and the Red Sox. He might turn out to be the first player to wear the pitching helmet.
