Former Chelsea winger Paul Canoville is critically ill in hospital after emergency surgery.
The 58-year-old was the club's first black player when he signed in 1981 and scored 15 goals in 103 games before retiring with a knee injury aged 25.
The Blues have wished him a rapid recovery, saying he "holds a major place in Chelsea history".
A statement from the Paul Canoville Foundation asked people to keep him in their thoughts.
