Lewis Hamilton suffered a crash on day two of his second Ferrari test in Barcelona, Italian media have reported.
The Brit and team-mate Charles Leclerc are testing a 2023 Ferrari at the Circuit de Catalunya over three days as they continue to prepare for the 2025 season.
It is Hamilton's second run in a Ferrari car after he drove 30 laps of the team's Fiorano test track last week.

The mileage counts towards the 1000km of testing that full-time drivers are permitted to compete in older cars across four calendar days each year.
But Ferrari's progress has been delayed after Hamilton suffered a crash at around 11am in the morning, various outlets have reported.
Hamilton is said to have 'lost control' of the car in the final sector of the track, subsequently hitting the barriers and causing 'rather serious' damage to the suspension and more minor damage to aerodynamic parts.

The seven-time F1 world champion is said to be fine after getting out of the car, though Ferrari are unsure as to what caused the crash and are now analysing their telemetry.
The test is being ran behind closed doors, meaning footage of the crash is unlikely to become available.
Ferrari's trackside operations at Montmelo are not being led by team principal Frederic Vasseur but by his deputy Jerome D'Ambrosio.
The Belgian formerly drove in F1 in 2011 for the Marussia Virgin Racing team, before making a one-off appearance for Lotus at the 2012 Italian Grand Prix after Romain Grosjean received a one-race suspension.

Motorsport.it reported that, ahead of the test, Ferrari were focusing on key areas for improvement during the three days in Barcelona.
Race starts and clutch usage were believed to be two main areas of focus, as well as tyre wear, given how the SF-23 struggled with overheating issues in comparison to the SF-24, which Hamilton has yet to drive.
Leclerc was due to take over running of the SF-23 in the afternoon on Wednesday, though that running has now been delayed as Ferrari explore damage to the car.

The Scuderia will run test drivers Antonio Giovinazzi and Dino Beganovic on day three of the test on Thursday.
