Was looking this weekend but couldn't see anything (at least from English language news).
I went back and checked the injury report and while a broken collarbone & fractured ribs are both annoying injuries they could definitely be recoverable from in time depending on severity (particularly with pro medicine and treatment).
Probably depends on whether he's able to get on the bike early & comfortably enough that he's riding freely, and I suspect the radio silence means they're weighing that up at the mo. If it was a gentler first week I think he'd race, but with MdB and a TT early and then a reasonably hefty first weekend it's easy to see him out of the race before it even really gets going if he's not at 100%. Perhaps better to just heal up and be freshest come La Vuelta.
