Arsenal manager Unai Emery has allayed fears about Emile Smith Rowe's fitness after their 5-0 win over Nottingham Forest.
The Gunners were successful in the Carabao Cup, but there was a negative in Smith Rowe coming off in the first half.
He was involved in a clash with Forest goalkeeper Arijanet Muric.
But Emery says that it is a minor issue that should not keep him out for very long.
"He received a knock in his head and it was for precaution that we changed him," Emery told the club's official website.
"But, I am thinking that it is going to be not a serious problem.
"It was one knock in his head."
