Australian rockers San Cisco have been forced to embark on their world tour without bassist Nick Gardner after he accidentally shot himself in the foot.

The musician was driving around a friend's farm when he reached down to move his gun, which had been bouncing around on the floor.

In a statement, he explains, "Before I knew it, it had gone off... I realised I had been shot and ripped off my boot and sock to reveal a hole in my foot and blood everywhere."

He was hospitalised and has since undergone treatment in Perth, where Gardner reveals "a specialist has done a great job putting my foot back together".

As a result, the bassist will have to sit out at least the first leg of San Cisco's upcoming trek, which kicks off in the U.S. next week (begs09Mar15).

A replacement musician will perform with San Cisco in Gardner's place.
