Playing two-over-one game forcing, there is no need to jump since you are already in a game force. Bid two spades to confirm the eight-card fit. Partner can continue describing his shape now, by bidding two no-trump, or three of a minor with 5-4-3-1 distribution, or repeating his spades, which typically shows six (or five excellent) spades and no convenient alternative call.
