There have been several more news items on the Rugby star's condition.
He is reported as recovering and still on regular dialysis, but has been given a slim chance of a "normal" life.
He has withdrawn from the charity boxing match mentioned in the previous article.
PS If you want to see what he was like as a player, just watch this compilation of him in action. There are many shots where he fends off three or more blockers simultaneously to get a touchdown. I noticed a couple of times when five blockers failed to stop his run; be amazed at his power.
