Giants rookie forward Marcus McKethan I tore my anterior cruciate ligament at Friday practice. On Saturday, the team announced that they had placed him on injured reserve for the end of the season.
The Giants selected McKettan in the fifth round, one of three offensive linemen selected by the team this spring.
He spent most of his time as a stand-in for the right guard, although he also snapped the right tackle. His injury leaves another dent in the depth of the team along the line.
offensive tackle Matt Gono left the team to check his neck for a possible career-ending injury.
On Friday, the Giants added veteran Tackle Will Holden as a replacement for Gono.
