Rhian Brewster will sit out Derby County's next two Championship fixtures after sustaining concussion during Saturday's 3-0 home defeat by West Ham United, manager John Eustace confirmed.

The 26-year-old forward lasted just 22 minutes before being forced from the pitch, leaving Derby to play the remainder of the match a man light in attacking options as West Ham ran out comfortable winners.

Eustace moved quickly to offer a positive update on the player's condition while making clear the absence will sting. "He's feeling a lot better," the Derby boss told BBC Radio Derby. "He was really groggy on Saturday night, he felt dizzy and sick during the game. It's a big blow because I was really excited to give him a run of games. He's a top performer at this level and he needs to get fit and get games under his belt, so it's a shame now for him to miss another couple."

Brewster, who joined Derby from Sheffield United in August 2025, had started each of the club's last two league outings and featured in all five of their Championship games this season before the injury struck. Eustace had been building a run of starts around him with the intention of bringing the forward to full sharpness, making the timing all the more frustrating.

The immediate concern for Derby is Wednesday evening's home fixture against West Bromwich Albion (19:45), which arrives before the squad has had meaningful time to regroup from the West Ham setback. A second game will also pass without Brewster before the concussion protocols allow him to return.

Concussion absences carry mandatory minimum lay-offs under football's return-to-play guidelines, meaning Eustace cannot accelerate the timeline regardless of how quickly the player recovers subjectively. The club will monitor him through each stage of the graduated protocol before clearing him for contact training.

The loss of Brewster adds to an increasingly testing injury picture at Pride Park. Derby have already been managing the fitness of several players in the early weeks of the campaign, and Eustace will need to reshuffle his forward line to cover the gap. Whether he opts to shift the shape or promote an alternative striker from within the squad remains to be seen ahead of the Albion game.

For West Ham, Saturday's victory extended their bright start at the top of the second tier. For Derby, the scoreline and Brewster's injury combined to make it one of the more painful afternoons of their early season. Eustace acknowledged as much, but his public message remained measured: the player is recovering well, and Derby must find a way without him for the next fortnight.

With Wednesday's clash against West Brom arriving quickly, Eustace has little time to dwell on what happened. The expectation is that Brewster will be assessed day by day, with a return possible around the middle of September if he clears every stage of the protocol without complication.
