Still no news, officially.
But I've managed to find out how David is spending this weekend.
Looks like he's playing a polo tournament in Córdoba and his team won its first game yesterday (source).
So I guess it's safe to say that his shoulder isn't really that bad.
It was the first thing we heard from David after the Davis Cup quarterfinal and his vacation afterwards,
the official statement published via the Argentine media on Saturday.
And so far, it's also the last thing we heard - not a word since then from David or his camp.
Neither about the "numbness" in his shoulder since playing the last Davis Cup doubles.
Nor about his plans for the coming months.
