Dodgers pitcher Josh Beckett has been diagnosed with nerve irritation and will not throw for four weeks.

Beckett was placed on the disabled list May 14 in part because of a sore groin, in part because of tingling and numbness in his right (pitching) hand. He met with Dr. Greg Pearl, a Dallas-based nerve specialist on Monday, who agreed with the team’s diagnosis of an irritated right ulnar nerve.

Dodgers manager Don Mattingly said that his staff hasn’t discussed sending Beckett to the bullpen once he returns to health.

Beckett will be back with the team tomorrow to continue his rehab progression.
