Let G be one of the following groups: L 3 ( q ) {L_3}(q) and G L ( 2 , q ) GL(2,\,q) with q ≡ 3 ( mod 4 ) q\, \equiv \,3\,(\bmod \,4) , U 3 ( q ) {U_3}(q) and G U ( 2 , q ) GU(2,\,q) with q ≡ 1 ( mod 4 ) q\, \equiv \,1\,(\bmod \,4) . This paper is concerned with 2-blocks B of G having semidihedral defect groups. In particular, vertices, sources and Green correspondents of the simple modules in B are determined and used to obtain the submodule structure of the indecomposable projective modules.
