Urban indicates all the interior positions on OLine are still open.  Said Pat Elflein may play center.  If he does Joel Hale, converted dlineman is play right guard and Billy Price will play left.  If Elflein stays at right guard, then Boren will start at center and Price will still be left.  No mention of Underwood who came out of spring as the tentative starter.
