Lets say it is pouring outside and at half time one of the team's jerseys are soaked. Can they change to a different jersey as long as it does not conflict with the other team/referees? B
Didn't Man U change shirts at halftime a few years ago, not because the shirts were soaked, but simply because they weren't playing well in them? I know this sounds ridiculous, but I remember Man U debuting an ugly gray 3rd shirt; either they switched at halftime or they played the whole game in them but never wore them again. So, to answer your question, I guess so.
LOTG only require that players have uniform jerseys that conflict with the opposing team. There's no rule that states they must wear the same jersey for the entire match. The answer is yes players may change their jersey so long as it is the same as their teammates. If the league requires rostered numbers then that would have to remain the same as well though, which is more unlikely at lower levels of play -- something the ref should be careful of. True story: heavy downpour of rain during last week of the youth division 3 league. The CR cautions a player for whatever reasons and soon thereafter calls for halftime. The team switches into their away jerseys, but the player that got cautioned now has a new number. Second half begins and that same player receives another caution but the ref and the other team didn't recognize him. The game concludes with that player ultimately scoring the winning goal. I would hate to be the league administrator for that incident
Technically, I don't believe there is any prohibition against changing jersies at the half. However, unless we're talking about a shivering bunch of 6 year olds, I wouldn't be inclined to allow it. Too much can happen with regards to the scenario given by Statesman. Besides, I'm out there too, dammit. If I have to wear my wet shirt, so do they.
None of us have changed sleeve lengths or jersey colors at halftime? If we'd allow ourselves to do it then I'd say we'd have to allow a team to do it, so long as every player retains the same numbers and that the new colors don't clash with the opponents. Unorthodox and extremely rare? Absolutely. Illegal? I don't see how.
Southampton v. ManUre at the old Dell Half time score S'oton 3 - 0 ManUre (I have that game on tape) ManUre was wearing a blue jersey that day and it had been noted that they lost big the only other time they wore it. They changed at half-time (to their solid white, I think) and the FA subsuquently fined ManUre for some rules violation - I don't think they cleared it with the CR.
They were wearing their "one season" grey away shirt and were getting trounced at half time, and ended up losing 6 - 2 to Southampton, and "blamed" the grey for blending in with the crowd. Can't remember what the "excuse" was after 90 minutes about the blue they wore for the second half. Must have "blended" with Ferguson's mood or language at the end of the game! (On the "technical point" the laws state that the two teams must be different from each other and the referee). (Don't often see that law being "envoked" when it comes to goalkeepers wearing black, in addition to the referee).
