Alex Zanardi remains in a stable but serious condition three days after the hand-bike accident in Italy that left the racer with traumatic head injuries.
Zanardi was airlifted to the Policlinico Le Scotte in Siena late on Friday afternoon where he underwent surgery for skull and face fractures following a crash in a relay race on a road in Tuscany.
According to several reports, Zanardi crossed into the wrong lane and into the path of an oncoming truck, which was unable to avoid him.
On Sunday, Zanardi's doctors said the driver's condition was not life threatening but insisted the "neurological picture" remained serious. The 53-year-old Italian is in an induced coma and on a ventilator.
The latest update from the Santa maria alla Scotte hospital said: "The clinical conditions remain unchanged in the cardio-respiratory and metabolic parameters while the neurological picture remains serious.
"The patient is sedated, intubated and mechanically ventilated and the prognosis is confidential.
"The multidisciplinary team that takes care of him will evaluate in the next few days any diagnostic-therapeutic actions to be taken."
