Further analysis of our i-band imaging from the 2.5 m NOT (Gorosabel et al., 
GCN 15512) of GRB 131122A (Gotz et al., GCN 15510), with mean epoch 
00:49 UT (3.40 hr after the burst), shows no new source within the Swift-XRT 
error box (Maselli et al., GCN 15513) down to a 3-sigma magnitude limit of 
i=23.5 (AB).
