The Australian has been sidelined by injury three rounds into his F1 return after crashing in second practice at Zandvoort.
He locked the front wheels into the banked Turn 3 to shunt into the barrier.
The steering wheel moved violently upon impact to result in a broken metacarpal in his left hand.
Ricciardo underwent surgery and “metal work” in Barcelona on Sunday and is believed to have been treated by renowned MotoGP doctor Doctor Xavier Mir.
On Monday, AlphaTauri confirmed that Lawson will deputise for Ricciardo “until he is fully fit.”
