The New York Giants placed Clint Sintim on injured reserve Friday, hours after the third-year linebacker suffered a season-ending knee injury.
Sintim, who has battled injuries during his two NFL seasons, was trying to come back from a season-ending torn ACL he suffered in the same knee in December, also landing him on IR.
"It's unfortunate," Sintim said, according to the New York Daily News. "I worked really hard to get back. And um ... it's just unfortunate."
"You've got to feel badly for a guy that's coming back off a serious knee (injury)," Coughlin said. "Works his tail off, really didn't say a word the whole preseason, just did what he had to do, worked on the field. And then to see that happen tonight. It was devastating."
The Giants also waived four players Friday: cornerback Darnell Burks, wide receiver Todd Watkins, guard Brant Clouser and defensive tackle Ibrahim Abdulai. Burks, Clouser and Abdulai are rookies. Watkins is a third-year pro.
