I just realized my post yesterday was not very well put. Tulasne said he won't play Dubai, period. The second part was just me "thinking out loud", he most probably won't play, don't worry.
(But in general, he seems to be the kind of guy who plays every week unless he's injured. He had even asked for a WC at the Bergamo Challenger before he was picked for the Davis Cup. For a Frenchie, he plays quite a lot!)
thanks Truc (as always).
I hope he will not play in Dubai because I think than now a week of training is important to be physically ready for American MS
