The Atlantic Coast Conference's coordinator of officials says it isn't clear whether a North Carolina State player stepped out of bounds during a critical play in a loss to No. 3 Clemson.
Doug Rhoads issued a statement Friday, one day after Clemson beat the Wolfpack 26-14.
Momentum swung on Bryan Underwood's long sideline run for an apparent touchdown. An official blew the play dead, ruling he stepped out at the Clemson 47. That prompted prolonged booing from the crowd.
N.C. State fumbled three plays later and Clemson followed with a touchdown to go up 20-7.
Rhoads says his office viewed "all available angles" numerous times and says some images seem to show Underwood didn't step out while another indicated he did.
Rhoads says it "cannot be resolved beyond all doubt."
