Brentford midfielder Josh McEachran picked up a knock during the defeat against Bristol City but the injury is not thought to be serious.
McEachran, who has been plagued by injury problems, was withdrawn at half-time and replaced by by Kamo Mokotjo.
But new head coach Thomas Frank insisted: “It’s nothing serious.
“He got a knock – not an injury. But it was better to get fresh energy on the pitch.”
