Giants' defensive end Osi Umenyiora is set to have an MRI after suffering a knee injury that forced him to leave the team's preseason game against the Jets, according to The New York Post. "Any time a guy like that goes down it definitely hits you right in the throat," Justin Tuck said. "Hopefully, it ain't that serious." Umenyiora left with 10:48 remaining in the second quarter of New York's 10-7 loss to the Jets. The Giants announced during the game that X-rays taken of Umenyiora's knee were negative, but that only means there are no broken bones. "Obviously, you can't replace Osi Umenyiora, but I feel we got guys who can fill in that role and give us some quality play," added Tuck. "We're not thinking like that right now. We're thinking Sept. 4, No. 72 [is] going to be right there at his normal spot at right end."
