Run-D.M.C. rapper Darryl McDaniels has been hospitalized in New Jersey, according to People magazine.

Doctors discovered two major blood clots after McDaniels complained of pain and swelling in his left arm, and was to undergo surgery Friday (7/18). No updates about his condition were available this morning (7/21).

McDaniels, who has been working as a solo artist since Run-D.M.C. broke up in 2002, had to pull out of a scheduled performance July 19 at the AVP Beach Volleyball Tournament.
