Tkaczyk is now being treated at Mary Free Bed Rehabilitation Hospital in Grand Rapids, Michigan, where he's undergoing physical therapy to allow him to walk, drive and play drums again.

Tkaczyk says: "We were all sleeping so I woke up in the debris. I was laying on my back and I looked down at my leg and I noticed my leg was absolutely broken. I couldn't feel anything - I was in shock. I remember laying there telling myself, 'Just keep breathing. You've got to stay alive for mom and dad, my brothers, for my friends and family.

"They got us in the chopper and flew us out, and that's the last I remember of the actual accident. I woke up in hospital 10 days later as I was in a medically-induced coma. I was already starting to think about ways to how I could go back to my normal life - my job. Right there off the bat I was like, 'Right, let's do this.'"
