Reminds me a bit of the injuries Jurgen Van den Broeck suffered in the 2011 Tour. He also had a punctured lung and broken scapula on top of that if i recall. He crashed on the 10th of July and the Vuelta started on the 20th of August (40 days later). While he wasn't bad in that Vuelta (8th in GC), he actually gave a very good impression in the Tour when he crashed. It was the only year i actually though he could have contended for yellow.Fractured collarbone and multiple broken ribs.

Anyway, JVdB's injuries were slightly worse but Landa has about the same timeframe to get ready for the Tour... or skip it and go for the Vuelta.
