Canadian actor Dean McDermott says he is on the mend after a motorcycle crash left him with a punctured lung.

McDermott has been sending out Twitter messages to his online fans, assuring them that although the injury was painful he was on the right track.

"I'm healing, slowly. I'll be doing rehab for a while. I messed a few things up when I crashed," McDermott said in a brief message sent Sunday.

People said Monday that McDermott also assured his readers he was feeling better and wished them a Happy Fourth of July.

McDermott, 43, is married to actress Tori Spelling and was in the cast of the television series "Due South." He wound up in the intensive-care unit of a Los Angeles hospital after cracking up his dirt bike June 29.
