Sources close to Mark Sanchez and USC tell ESPN's Chris Mortensen that the quarterback plans to announce Thursday that he will forgo his senior season to enter the NFL draft. Sanchez's father Nick Sanchez told ESPN's Shelley Smith on Wednesday his son is undecided. "Mark is waiting for Coach [Pete] Carroll to return from Hawaii, which is tonight," Nick Sanchez told Smith. "Mark didn't want to do anything without Coach Carroll." Nick Sanchez said his son will meet with Carroll either Wednesday night or early Thursday. "Mark has gone both ways on this," Nick Sanchez said, "and he is still undecided."
