IRVING, Texas – DeMarco Murray made a quick appearance in the Dallas Cowboys’ locker room on Tuesday, less than 24 hours after undergoing surgery on his left hand. Murray was sporting a heavy wrap on his hand, but he said he felt great. He also said he has done a fair amount of research on his injury – a fractured fourth metacarpal in his left hand – and was expecting to talk with Emmitt Smith, who suffered a similar injury in 1999.
