    Field theory on a fuzzy noncommutative sphere can be considered as a particular matrix approximation of field theory on the standard commutative sphere.We investigate from this point of view the scalar Ø4 theory. We demonstrate that the UV/IR mixing problems of this theory are localized to the tadpole diagrams and can be removed by an appropiate (fuzzy) normal ordering of the Ø4 vertex. The perturbative expansion of this theory reduces in the commutative limit to that on the commutative sphere.
