Where has Anthony Elzy been?

CHAPEL HILL, N.C. -- This is a question I can't answer. UNC running back Anthony Elzy, who picked apart Virginia Tech's defense in the first half, has been a non-factor in the second.

He was so invisible, in fact, that the sports information office was checking to see if he was injured. On UNC's second possession of the fourth quarter, he was back on the field and rushed for seven yards. If he's healthy, it's hard to explain his disappearing act.
