Corticosteroids may be banned

Corticosteroids, which are used in anti-inflammatory medicines to treat a range of conditions, are allowed out of competition by athletes and permitted in competition by obtaining a therapeutic use exemption.

Last year Carter, along with Racing 92 team-mates Rokocoko and Juan Imhoff, created international headlines when traces of corticosteroids showed up in drugs tests taken by the trio following last season's Top 14 final in Barcelona.

Carter cashes in on new sponsor

Carter has been signed by watchmakers TAG Heuer, who have made him a brand ambassador.

The Swiss company has announced via Twitter: "Are you ready for fantastic news? We are so proud to present New Zealand rugby super player Dan Carter as our newest TAG Heuer Ambassador".

The company's other ambassadors include the American football quarterback Tom Brady and football superstar Cristiano Ronaldo.

Land Rover dropped Carter last month, a decision Carter said was not suprising.

Carter home and makes another apology

On social media Carter posted: "Just got back in New Zealand for what was supposed to be a fun pre planned holiday.

"Seeing the family again puts fresh perspective on just how big a mistake I made. #dontdrinkanddrive."

Carter made an apology on Facebook yesterday after being caught drink driving in Paris, saying he was glad no one was hurt.

The French newspaper L'Equipe reported Carter was stopped on Wednesday by police and had a blood alcohol concentration nearly twice the legal limit.
