Newly acquired Red Sox infielder Curtis Mead has a non-displaced fracture in his left wrist and will be reevaluated in four weeks. Interim manager Chad Tracy announced Thursday, three days after Mead left his debut after being hit by a pitch from Athletics starter Jack Perkins.

Mead returned to Boston to see a hand specialist and was placed on the injured list Wednesday after follow-up tests confirmed the break. Boston traded young left-hander Connelly Early to the Nationals for Mead over the weekend. Mead is hitting .253 with 17 home runs and 48 RBIs this season.

Also Thursday, Tracy said outfielder Roman Anthony has started swinging a bat again in Fort Myers, Florida, where he continues to rehab a finger tendon injury that has sidelined him since early May.
