Portsmouth Football Club have reluctantly taken the decision to postpone the League One home fixture against Southend, which was scheduled to take place next Saturday (September 7).
A request to call the game off was accepted by the EFL, with the Blues having three players selected for international duty.
Ronan Curtis and Craig MacGillivray are in the Republic of Ireland and Scotland senior squads respectively, with Ross McCrorie representing the Scottish under-21 side.
Pompey manager Kenny Jackett said: “We had the three boys called up by their countries and then Marcus Harness was injured at Blackpool.
“He’s expected to be out for 7-14 days with a thigh strain, which would have left us without four of our starters from the last game.

“Because of that, we have reluctantly taken the decision to postpone next Saturday’s match against Southend.”

Pompey’s next League One match is now against Burton at Fratton Park on Tuesday, September 17.
Before that, however, Crawley visit in the group stage of the Leasing.com Trophy on Tuesday, September 3 (7.45pm kick-off) and tickets are on general sale.
