The If the Boot Fits singer was performing at the Starland Ballroom in Sayreville on Friday (02Dec16), when a monitor the 37-year-old was standing on collapsed, causing him to fall onto a metal barricade.

Smith played through the pain to finish the show, but was subsequently hospitalised with two broken ribs and a collapsed lung.

He axed his scheduled gigs over the weekend (03-04Dec16) as he remained under doctors' care, and was discharged on Tuesday (06Dec16), when he returned home to Texas to recuperate.

Sharing a photo of himself resting on a couch online, he wrote, "Update: Out of the hospital, back in TX & starting to regain movements. The outpouring of support has me feeling VERY blessed. Thank y'all!"

In a statement thanking medical staff for taking care of him, he says, "I truly appreciate all the doctors and nurses at Robert Wood Johnson University Hospital. Their resolve and professionalism were reassuring during a pretty rough few days for me."

Smith has also scrapped the remainder of his shows for December (16), but has promised fans he will make the effort to reschedule each date.

"I've had so many emails and tweets," he continues. "It's pretty amazing that so many people have reached out from across the country. I feel so blessed to have more than just support for my music from fans and radio. It's deeply humbling to have fans that personally care so much."

The affected concerts include stops in Florida, Tennessee, Las Vegas, California, and Kentucky.
