OT remark: Jesus. I work with the elderly, mostly. I would love to have her clarity of thought if and when I reach her age. I've heard before that playing chess retains hair loss and mental deterioration, especially in the elderly.

Could it also have been a black rook as well?

No. A Black rook would have allowed black to b8b7 and block the white rook from the final checkmate. A knight, on the other hand, would not be able to block the white rook and would therefore result in a checkmate.
