GCN 23707) like that of GRB130427A\n(De Pasquale et al. MNRAS 462 (2016) 1111) may provide another critical\ntest of GRB theories. In the Cannonball (CB) model, the X-ray afterglow\nof very bright SN-GRBs is expected to decay like a single power-law in\ntime and in frequency, Fnu ~ t^{-alpha} nu^{-beta}, where for a constant \ndensity ISM the temporal and spectral indices satisfy alpha=beta+1/2 and \nthe \"missing break\" is hidden under the prompt emission (Dado & Dar, PRD \n94 (2016) 3007). The current values alpha=1.34+/-0.01 and beta=0.82+/-0.12,\nreported for GRB190114C in the Swift XRT light curve repository (Evans et \nal. 2009) seem to satisfy well the above CB model closure relation, which \nsuggests an SN-GRB association similar to SN2013cq-GRB130427A.",
