Bunch of medical updates on Pirates pitchers

A.J. Burnett's simulated game went without incident. He will be re-evaluated this afternoon. There are no details available about when he might make his next start. (Burnett is currently participating in infield drills. He is fielding balls hit back to the mound, charging bunt attempts and running the cover first play.)
