Rob Gronkowski is out for the rest of the 2013 season with a torn ACL and MCL in his right knee.
Bill Belichick said Monday that he didn't expect to receive positive news on Gronkowski's injury.
"Rob's going to have some more tests today, but that situation doesn't look too good," he said. "We'll wait until we have a final evaluation to confirm or do anything."
Gronkowski was slow to begin his 2013 season due to a recurring elbow and back injury, but had returned to his prior form.
