Alistair Johnston will miss Celtic matches until November due to injury

Celtic defender Alistair Johnston is sidelined with a hamstring injury, expected to return in November. The Canadian international was substituted at halftime during a 5-0 victory against Kilmarnock earlier this season. Celtic management anticipates needing to bolster their defense and is in discussions to potentially sign Niko Sigur from Hajduk Split or Yuki Sugawara from Southampton. Colby Donovan, who performed well against LASK, may continue as a starting right-back until a new signing is secured.
