The Athletic reported the news regarding McArthur’s injury and it could derail the side’s preparations ahead of the upcoming season.
The Scot has suffered a groin injury and will miss the first league match of the season against Arsenal, and with the setback of missing pre-season, it might take longer for the injury to heal.
The 34-year-old missed a big chunk of last season following a torn hamstring in November which kept him out until February, with further niggles restricting the player to just 15 league starts overall.
This news will be a big worry to Vieira with one of his most experienced players will be missing the crucial opening match of the new season.
The Scot recently signed a one-year extension to his current contract which will see him enter his ninth season at the club and his absence will be a big blow.
Although Palace had a solid season last year, finishing 12th in the Frenchman’s maiden Premier League managerial role, there are hopes that this can be improved upon this season.
With McArthur missing, his leadership will be tough to replace and other members of the squad will be required to step up.
The injury meant Vieira looked to delve into the transfer market, but missed out on key target Flynn Downes to West Ham and have seen Conor Gallagher return to Chelsea, although a deal appears to be close regarding the signing of RC Lens midfielder Cheick Doucoure, which could soften the blow of losing McArthur.
Vieira will be hoping for McArthur to replicate his form from 2019/2020, where he made 0.9 key passes, 2.4 tackles, and 1.6 interceptions per match, as well as registering three assists and completing 66% of his dribbles, proving his ability to be a key component of the side.
Hopefully, the club can manage the injury well and get the player back up and running as soon as possible.
