EFL League One side Portsmouth are in danger of having their Leasing.com trophy game away at Oxford United and their league fixture at home to Gillingham postponed.
Ross McCrorie has been called up for the Scotland Under-21s, who he has captained in the past, while winger Ronan Curtis has been called up for the Republic of Ireland senior squad and goalkeeper Craig MacGillivray has been called up for the Scotland senior team.
The Scotland U21s host Lithuania U21s on 10th October, while travelling to the Czech Republic four days later, and for the senior squad, they face Russia away on 10th October before returning to Scotland and hosting San Marino three days later.
The Republic of Ireland senior squad face two away games however, travelling to Georgia on October 12th before heading to Switzerland on the 15th October.
Portsmouth are due to face Oxford United on the 8th October, before hosting Gillingham on the 12th October.
McCrorie, on loan at Portsmouth from Rangers, has made 14 appearances for the Scotland U21 side, while MacGillivray is yet to receive a cap but was called up for the first time for the September internationals by Steve Clarke. Curtis has three international caps since making his debut last year.
Portsmouth would be better off postponing the two games that could well be affected by the international call-ups, especially the league game with Gillingham. MacGillivray is vital in the Portsmouth net as an ever-present this season, while Curtis has scored twice in his eight league games this season.
Despite only featuring in five league games this season, McCrorie has been an unused substitute in the other three league games and has a part to play at Fratton Park whatever the circumstances.
