Monster-Cianciarulo-Off-Road-5-9-13Irvine, Calif. Monster Energy/Pro Circuit/Kawasaki rider Adam Cianciarulo will undergo surgery today to repair his left shoulder. The surgery is expected to sideline Cianciarulo for three-to-four months.

“This setback is very disappointing,” said Cianciarulo. “We had a great start to the supercross season and I wanted to win a championship for my Monster Energy/Pro Circuit/Kawasaki team. As much as I would love to tough it out like I did last weekend, the people around me and I feel this is the best decision to fix my shoulder for good. I know I will come back stronger and ready to compete as soon as I can.”
