Ant McPartlin was left wincing and clutching his arm after crashing a monster truck on Ant And Dec's Saturday Night Takeaway.
The presenter went head-to-head with Declan Donnelly in a live monster truck race as the programme returned to screens on Saturday night.
Ant surged over a ramp at the end of his final lap before crashing into two stationary cars.
He labelled the race a "tough, tough challenge" as he emerged from the vehicle holding his left arm before joining Dec and fellow presenter Stephen Mulhern.
Ant won the first challenge of the series after Dec spun his truck in the wrong direction.
He appeared fine as he returned to perform alongside Dec and Kylie Minogue later in the programme as the pop star performed a medley of hits.
The crash came just a day after the pair admitted practices for the challenge had not been going well.
Ant admitted the trucks cost "a couple of hundred grand", so there would have to be "no more crashing".
