Rivera was inadvertently poked in the eye during Sunday's loss to the Arizona Cardianls and suffered severe bruising and double vision. Tests alleviated fears of a broken eye socket. Rivera is currently wearing a patch but said he will try to avoid donning a protective shield on his helmet.
Rivera, who has a streak of 70 consecutive games including playoffs, already is playing with a torn MCL.
Ferguson again aggravated his knee injury, but an MRI showed no further damage.
