Celtic manager Martin O'Neill has confirmed that two key players, Kasper Hogh and Kieran Tierney, could be available for Wednesday's Scottish Premiership match against St Johnstone. Both players are nearing their returns from injury, and O'Neill said the team will assess their fitness before the game. Hogh, a Denmark international and Celtic's record summer signing, has not played since late August, when Celtic lost their Champions League play-off against LASK. Tierney, a Scotland defender, missed recent matches against Aberdeen and St Mirren. O'Neill noted that Hogh has been back with the team for the past couple of days, while Tierney did some light training on Tuesday. The manager emphasized that the decision on whether they will play will depend on how they feel on Wednesday. He also mentioned that there are other fitness concerns among the squad, but the team will aim to field the strongest possible lineup. O'Neill expressed cautious optimism about Hogh's potential return, noting that the player had an extra day to recover. He said the final decision on whether Hogh and Tierney play will be based on their condition on match day. In Hogh's absence, Camilo Duran, another high-profile summer signing, has performed well in the center-forward role, scoring six goals in eight games. When asked if Duran might move to a wider position upon Hogh's return, O'Neill said the focus would be on fielding the best players available. Celtic will be without winger Yang Hyun-jun for Wednesday's match as he competes in the Asian Games. O'Neill called Yang's absence a "big miss," highlighting the South Korea international's strong performances this season, including scoring crucial goals and maintaining a high work rate. Yang will miss the next four matches for Celtic. Celtic are set to face Rangers in a derby match on Sunday, but O'Neill emphasized that Wednesday's game against St Johnstone is of greater importance. The team is focused on defending their Scottish Premiership title and securing a win in this match.
