Phil Collins' Health Condition

It is given that Collins had to sit down throughout the remainder of their show as he is currently suffering from a medical condition.

Since he used to be the band's drummer, he mentioned that he can barely hold a stick and he was physically challenged by the situation leaving him very frustrated.

However, the band still has a drummer as he was replaced with his son, Nic, and he will be touring with them for the rest of their tour dates.

"I'm kind of physically challenged a bit whichs very frustrating because I'd love to be playing up there with my son." Collins said earlier this month.

He mentioned that his son "plays a bit" like him and he became Nic's influence when it comes to music.

"he kinda has the same attitude as me, so that was a good starter." Collins described his son.

The legendary mucisian has been suffering from nerve damage due to a spinal injury that occured in 2007. The situation left the vertebrae in his upper neck damaged.
