English football is currently suspended until 30 April due to the coronavirus pandemic, with the decision confirmed on Thursday after a meeting of the sport's governing bodies.
No date for the Premier League or English Football League to resume is pencilled in, but one big issue is players who will be out of contract on June 30.
It has added to growing speculation everything will be done to complete the 2019-20 season by that point.
Semmens admits playing into July would create a new set of issues for football clubs although he believes they could work out an arrangement with the players that would see them extend their deals on a short-term basis.
