New York Giants quarterback Daniel Jones has been ruled out for the rest of the season after sustaining a torn ACL in his right knee.
Jones was injured late in the first quarter of 30-6 loss to Las Vegas on Sunday and the NFL club confirmed the diagnosis following an MRI scan.
The news came as a further blow to the Giants, whose latest defeat left them languishing on a 2-7 record after making the play-offs last season.
Undrafted rookie Tommy DeVito finished the game against Las Vegas but Giants head coach Brian Daboll would not be drawn on immediate plans for a replacement.
First-choice backup quarterback Tyrod Taylor, who played seven games while Jones recovered from a neck problem, has been ruled out for at least four weeks following a rib injury.
Veteran Matt Barkley is another short-term option in the position having signed to the Giants practice squad at the end of last month.
