Newcastle players Dwight Gayle and Aleksandar Mitrovic will miss the key Championship match against Brighton on Saturday.

The pair both suffered concussions during the 2-0 cup win against Cheltenham.

Newcastle have revealed on their website that they are adhering to the FA’s Concussion Guidelines and they will be absent for a period of at least six days.

Paul Catterson, Newcastle’s head of sports medicine and science, said: “The treatment and management of concussion in sport has received deserved attention in recent years.

“We have to adhere to the guidelines set out by the FA in line with other competitive sports, which rightly puts the safety and health of players first.”

Mitrovic was competing in his first game of the season after being suspended for the club’s first four matches, following his red card against Tottenham in the final league game of last campaign.

The Serbian striker has scored nine goals for Newcastle in 37 appearances across all competitions, since moving to St James’ Park last summer.

Mitrovic, 21, lasted just 38 minutes before he was forced off with a head injury and replaced by the club’s in-form striker Gayle.

Gayle has enjoyed a successful start to his Newcastle career with four goals in the league, more than anyone else in the Championship.

Gayle was then forced off early in the second-half with a head injury, and the pair will be a big loss at the weekend.

Forward Ayoze Perez scored the two goals to defeat Cheltenham and is expected to lead the line against Brighton, who are undefeated in their first four league games of the season.

The match is being broadcasted on Sky Sports at 5:30pm.
