British driver Paul Green and his co-driver Matthew Harrison both remain in a serious condition in hospital after an accident in the Dakar Rally.
The Team Desert Warrior duo were hurt in Saturday's first stage when their Rally Raid UK car flipped over in Trenque Lauquen in Argentina.
Green suffered a heavy blow to the thorax and the spinal column while Harrison also suffered a thorax injury.
Security fears mean the race has moved from Africa to Argentina and Chile.
Juan Enemeterio, chief doctor of the Hospital Modelo of Santa Rosa's intensive care unit, said about Green: "There are hopes of recovery, but we'll wait 24 hours to see whether he can be moved to Buenos Aires. He is connected to a respirator, and his condition is serious."
Harrison remains in an induced coma but it is expected that both men will be brought out of their comas on Thursday.
The race features 540 competitors from 50 countries and covers 9,000km spread over 13 stages - three in Chile and 10 in Argentina - with the finish scheduled for Buenos Aires on 18 January.
