New Zealander Liam Lawson will make his Formula One debut with AlphaTauri at the Dutch Grand Prix after Australian Daniel Ricciardo broke his wrist, the Red Bull-owned team said on Friday.
Ricciardo crashed at turn three in the day's second free practice session at Zandvoort and was taken to hospital for further checks.
"An X-ray confirmed he sustained a break to a metacarpal on his left hand, and this injury will not allow him to continue his duties," AlphaTauri said in a statement.
Lawson, 21, is the team's official reserve driver.
