Malukas, 22, is entering his third season in the IndyCar Series but first with Arrow McLaren after being confirmed to its 2024 lineup in last year’s season finale at Laguna Seca.
According to a team representative, the Malukas sustained the injury while “biking out west”.
Although a facture has been confirmed, the current plan is for him to undergo an operation on Tuesday afternoon.
It is not known at this time if the Chicago-born Lithuanian American be sidelined for any races to start the year.
“From there we’ll have a better understanding of a recovery window,” said the team representative, via an email Monday night.
Arrow McLaren signed Malukas to drive its No. 6 Chevrolet following the contract fallout drama surrounding reigning and two-time IndyCar Series champion Alex Palou, who opted to remain with Chip Ganassi Racing despite a previously agreed contract with McLaren.
Malukas spent each of the past two years driving for Dale Coyne Racing with HMD Motorsports, scoring two podiums (both in St. Louis), including a runner-up, in 34 starts.
