Good post agree

Do you have any evidence to support your theory? I would be unhappy if any player received painkillers both before a match and then again before he was able to return to the field.

None whatsoever, but it's common knowledge that players do get "jabbed up" before games.
Carlos missed a game last year when he lost all feeling in his arm before the match.
Whether it's right or wrong I don't know, but as long as the player gets the right medical advice then I'm (fairly) happy with it.

Taken from your website.....

I appreciate what you say. What evidence do you have that he gets the needle before and during matches? The first appears to be a fairly common occurrence at this time of the season. However I have not heard of anyone getting a second jab to allow them to re enter the field. Would not have thought the medics would be too keen on that.

I doubt there would be time at half time for a pain killer to kick in, and the risk of numbness etc.

As I said before, none.
I just said "I reckon", based on his game pattern - over playing himself (in my opinion), coming off much sooner than earlier in the season, and staying on the sidelines for longer.

Good old Google suggests Gavin Henson "played in their Six Nations victory over England at Twickenham but needed a painkilling injection at half-time as he struggled with an Achilles injury."
