Thomas Castaignede's physical and mental battle back to fitness after a 14-month injury nightmare is being aided by his club-mate Tim Horan.

Horan, the Saracens backs coach, is uniquely qualified to offer advice and support after suffering a career-threatening ligament and cartilage damage in his left leg in 1994.

"I was lying in a hospital bed in Brisbane on my 24th birthday when the doctor came in and told me it was very unlikely I could ever play rugby again," he told the Evening Standard.

"I'm sure negative thoughts have entered Thomas's head during his period out of the game and I have talked to him about handling it.

"I took the attitude that if I wasn't going to play again then at least I had won the World Cup in 1991 and had 30 caps for Australia.

"Being able to walk without any pain was the first boost and then it was a case of just waiting to be fit enough to have a game of tennis with friends and play a bit of touch rugby.

"Eventually, I was able to play in the 1995 World Cup after more than a year out but it was still another six months before I felt right about the leg.

"Thomas has another three or four months of hard work to do and he wants to be able to play a couple of games for Sarries before the end of this season.

"Significantly, Thomas can now walk without any pain and the doctor has given him the all-clear."

Horan has yet to play in the same Saracens team as Castaignede, who has missed 38 club matches since damaging his Achilles.

Horan said: "Playing alongside Thomas is one reason why I am going to make sure I am fit and raring to go for next season.

"It will be great to see him back in action for the club and there is no doubt that Thomas is a special player.

"Thomas just needs more time and has that on his side and although he is very frustrated, he is a good listener and realises that he's on track.

"There is a smile back on his face and there is no need to rush anything."
