Leg and foot swelling during air travel is common in uninjured persons due to just sitting with little movement for long periods of time. It's usually harmless. Leg injuries, especially those involving fracture,
that already have significant swelling to begin with, could in some cases place additional pressure on the veins, disturb venous circulation and increase risk for blood clots forming. This is many times, especially in the case of more recent lower extremity injuries, why players are not allowed to travel with their teams.
As far as Watson, he was dealing with a cracked rib, a contused lung, and a partially collapsed lung (pneumothorax)..............conditions that could worsen his lung function, encourage further lung collapse and encourage blood clots to block main circulation to the lung (pulmonary embolus).
