The weather is looking like it may be a factor in the bout between Wladimir Klitschko and David Haye. With it being an outdoor event, the fact that it is raining very hard and has been for quite some time is a concern. It was decided yesterday that fighters will wear “boots” to the ring to not track water onto the canvas but it’s still not ideal conditions for a fight.

Rain issue was discussed at Friday rules meeting. IF fight had to be called for weather before 4th round ended it would be a no contest.less than a minute ago via web

Fight is a go but I'm told powers that be have huddled to discuss possible alternative plans IF (IF!) weather is THAT bad. #dontpulloutnowless than a minute ago via web Favorite Retweet ReplyDan Rafael

No danger of the fight being called off, they have a canopy over the ring. Not much of a canopy, apparently no-one wanted to pay for it...less than a minute ago via web Favorite Retweet Reply

We’ll keep you up to speed on any major changes, but as of right now there looks to be no danger of the fight being called off.
