Here’s the statement from the Sox on Red Sox closer Jonathan Papelbon (attributed to Sox medical director Dr. Thomas Gill):
Jonathan Papelbon continues to improve each day. Recent examination and testing are consistent with a transient subluxation event in the setting of a fatigued shoulder. After a period of rest, he will begin a shoulder strengthening program.

Papelbon was removed from his last appearance on September 1 versus Toronto with discomfort in his right shoulder. He is 4-2 with a 0.92 ERA and 35 saves in 59 appearances with Boston this season.
Essentially, Papelbon had a slippage in the shoulder joint because of fatigue in the area. No timetable was announced at this time.
