New York Giants defensive tackle Shaun Rogers is being treated for a blood clot in his left calf.
The Giants announced Tuesday that the 12-year veteran was seen by orthopedic surgeon Russell Warren and vascular surgeon John Karwowaki on Monday at the Hospital for Special Surgery in New York.
Rogers experienced swelling in his lower leg after playing in the preseason opener Friday. He missed practice Sunday and Monday.
The Super Bowl champions did not say how long he would be sidelined, but New Jersey Devils defenseman Henrik Tallinder missed a couple of months this past NHL season after developing a blood clot in his leg.
