Notre Dame coach Brian Kelly disputed two calls late in the Irish's game against Pittsburgh on Saturday, but one in particular goes to the heart of the spread offense -- receiver Theo Riddick was called for a pick when he went across the middle, nullifying a 33-yard touchdown pass from Dayne Crist to Michael Floyd that would have given Notre Dame a 30-17 lead with less than six minutes to play.

''I just disagree fundamentally with the call,'' Kelly said. ''I've watched it a number of times. I'll have a conversation with our supervisor of referees. I've been running that play fo a long time and never had it called, because we run it the right way. That's a conversation we'll have to have and straighten out.''

The other call was an incomplete pass on Pittsburgh quarterback Tino Sunseri, who spiked the ball in the end zone without a penalty.
