Telegraph: Nottingham Forest defender Ainer suffered serious injury and may be out until the end of this year

British media Daily Telegraph reported that Nottingham Forest defender Ola Eina suffered a serious injury, which caused Postkoglu to suffer setbacks in the early days of coaching.

After Ena's hamstring injury is due to a few months of absence, Postkoglu may face the situation where Ena will not be able to use it until the end of the year.

Ener was substituted in the 10th minute in the World Cup qualifiers against South Africa on Tuesday. Scans showed that under the most optimistic situation, he also needed a truce until early December.

Ener has played every minute of the Premier League so far this season, and is a key player in Nuno's coaching period last season. Aina's long absence means he has been excluded from the Premier League registration list submitted by Nottingham Forest. It is reported that due to Ener's injury, striker Avoniyi, who had previously lost the UEFA Cup roster, will be added to the domestic competition list.

Ener's absence brought difficulties to Postkoglu's arrangement against Arsenal away, and new aid Zinchenko was unable to play against his parent team due to the avoidance clause. Internal Medicine Williams may switch from left back to right back, or Savona, who has introduced £13 million this summer, has made her debut.
