The No. 1 overall draft pick who has wowed coaches and teammates during the first two days of training camp practice will dress in full pads for the first time Wednesday afternoon.

Some defensive players expect this year's practices to be more intense and that they hope to break in the rookie with some interceptions.

But Luck doesn't have to worry about getting hit. He'll be dressed in a red No. 12 jersey, telling players it's hands off — something linebacker Robert Mathis says is necessary to keep Luck healthy for the regular season.
