According to an interviewI read with Michael Muhney, he had a terrible accident on his ATV.
He, his brother, grandfather, dad and uncle were four-wheeling in Vail, Co. when, while driving slow and with a helmet on, went to the top of a path where there is an overlook. They were going back down the hill when Adam's (Michael Muhney) ATV started to flip. He had to dive off, cracking his helmet open and snapped his collarbone. Rescue workers told him that if he had not of been wearing his helmet, he would not have survived.
He did not have to undergo surgery and does not have to wear a cast. Adam stated, Y&R has been able to shoot around the injury. He is only wearing a sling.
He is stated he will be able to continue the role of the duplicitous Adam.
