Primož Roglič is at altitude camp and is supposed to ride the Dauphiné in a little over a week, but we'll see. Jonas Vingegaard was also supposed to ride the Dauphiné but he's now out and is just looking to return for the Tour, reportedly through training in Mallorca. (It probably sounds more fun than it is.)
Remco Evenepoel and Mikel Landa haven't returned to racing, but they are both training together as they aim for the Tour. Sean Quinn is back to racing, and just won the U.S. Road Race National Championships in a tight sprint over Brandon McNulty, which was pretty fun to watch. Steff Cras is reportedly training with Wout Van Aert right now, but hasn't returned to racing.
Jay Vine is just happy to be walking again, but I haven't seen any news about him even returning to training. I can't find any news about Natnatel Tesfazion, but he had some of the worst injuries, so he's probably like Jay Vine and just working on recovery.
Also, though his crash was separate from the mass crash, Tom Pidcock had also crashed in Itzulia, but he's back to mountain bike racing.
