WWE Champion Drew McIntyre set to open Raw tonight

One night after vanquishing The Legend Killer at SummerSlam, Drew McIntyre will open Raw tonight.

The WWE Champion called the victory over Randy Orton the most satisfying moment of his career. After The Apex Predator left numerous icons in his wake, McIntyre came into the WWE ThunderDome determined to halt his path of destruction. McIntyre's pride in his accomplishment was evident in his eyes as he hoisted the title, but the fighting champion still refused to look away from The Viper.

What will be McIntyre's next move on the red brand, and will he have a message for the battered Orton?
