Crawford (wrist/illness) will throw a live batting practice session Friday, Tim Healey of The Boston Globe reports.
It will be the first time the right-hander has faced hitters since he suffered a wrist injury last summer that required surgery. Crawford has been brought along slowly in Red Sox camp post-surgery and also had a bout of the flu. He appears likely to begin the season on the injured list, though the Red Sox have not confirmed as much yet.
