Daniel Ricciardo is stepping up his recovery from hand surgery that has derailed his Formula 1 comeback.
The Australian driver has already missed both the Dutch and Italian Grand Prix following a heavy crash in practice in the Netherlands.
Ricciardo smashed into the wall at turn three in second practice in his bid to avoid compatriot Oscar Piastri, who had done the same moments before.
The eight-time race winner was later diagnosed with a broken metacarpal in his hand and needed emergency surgery.
Ricciardo has since been replaced by Red Bull junior driver Liam Lawson, who has finished 13th and 11th in his two F1 races.
But the 34-year-old will be itching to pencil in a return date for AlphaTauri, with a seat for the 2024 season in high demand.
Will Daniel Ricciardo return for the Singapore Grand Prix?
Ricciardo is unlikely to make his second F1 comeback of 2023 at the Marina Bay Street Circuit in Singapore this weekend.
The former McLaren star had originally earmarked the night race as his potential return date.
But Red Bull principal Christian Horner has since admitted Ricciardo will likely miss out having got a metal plate and some screws to secure the bone in his hand.
Ricciardo will be lacking fitness and Singapore’s humidity and the street circuit nature of the track has made it renowned for being one of the hardest races on the grid.
Speaking at Monza, Horner said: ”I think certainly Singapore, I don’t think there’s any chance he’ll be ready for then. I think it would be optimistic for Japan.
“But I think his recovery is going well, he’s got obvious mobility of the hand, he’s into rehabilitation now.
“We’ve seen with motorcyclists rushing comebacks can sometimes do more damage, so we just want to make sure he’s fully fit before he gets back in the car.”
