Let K be a finitely generated field of transcendence degree 1 over a finite field, and set . Let be a Drinfeld A-module over K in special characteristic. Set and let Z be its center. We show that for almost all primes of A, the image of the group ring in is the commutant of E. Thus, for almost all it is a full matrix ring over . In the special case it follows that the representation of on the -torsion points is absolutely irreducible for almost all .
