BoxingScene.com's Ronnie Nathanielsz reports that WBO welterweight champion Manny Pacquiao is skipping out on training to rest off a possible sinus infection. Pacquiao reportedly woke up with cold-like symptoms. Trainer Freddie Roach, while not too concerned, has ordered him to rest and wants to prevent outsiders from entering the training camp. Nathanielsz says there should be some concern because Pacquiao has a habit of avoiding medicine and places his faith in natural healing. 

"Pacquiao didn't train today. He is not well. Suspected sinus problem. Trouble is he depends too much on natural healing. Time for concern," Nathanielsz said.

Pacquiao is training in the Philippines for his fight with Antonio Margarito on November 13 at Cowboys Stadium in Arlington, Texas.
