DeMar DeRozan found out about his snug for the rookie challenge from Sonny Weems who burst into the training room where DeRozan was getting treatment for two sprained ankles and vented his own frustration at the snub.

DeRozan said he was "more confused than angry" about not being selected but he did use his Twitter account to share his initial feelings when he found it. DeRozan sent out the three-letter tweet "Wow".

"I've learned from other players, just keep it short and sweet," he said.

DeRozan said he will certainly be using this as motivation for the rest of the year.

"I don't get too frustrated because I've got an entire second half of the season to go," DeRozan said. "It's just a chance for me to show them that I should have got a mention here."

DeRozan will still participate in the dunk-off against Eric Gordon.
