We prove that the restriction of any nontrivial representation of the Ree groups 2 F 4(q), q = 22n+1 ≥ 8 in odd characteristic to any proper subgroup is reducible. We also determine all triples (K, V, H) such that K ε {2F4(2), 2F4(2)′}, H is a proper subgroup of K, and V is a representation of K in odd characteristic restricting absolutely irreducibly to H.
