Yes they will as they are classed are sporting equipment
quote from the VS web site:
All items of sporting equipment such as skis (with one pair of poles and one pair of boots), rucksacks, sleeping bags, and bicycles will be considered as one piece of luggage. Excess charges will apply.We have special rates for carrying sports equipment. For more details, please contact Reservations.
If it's the same as golf clubs that is, as long as each one is under the normal baggage allowance weight (ie 23K for Y or 32k for W or J on US flights or 23K in all classes on all other non-US flights) you wont need to pay any excess. Give VS or FC a call though to double check.
