Lotterer was under attack from the Mahindra of Rowland, and an optimistic lunge from the Brit into Sainte Devote at the start of lap 19 put the German driver into the wall, with Rowland also ending his own race in the process with damage.
This brought out a safety car, and the incident left Lotterer with a small cut and a pronounced bruise on his left hand - but he explained that there are no other injuries.
