Huddersfield midfielder Gary Roberts is facing at least six weeks on the sidelines after suffering a broken arm at Swindon.
Roberts landed awkwardly following a challenge from home captain Jonathan Douglas with just 15 minutes on the clock and had to be stretchered off at the County Ground.
The 26-year-old was immediately taken to hospital where X-rays confirmed the break before a cast was fitted and he travelled home on Saturday night.
He is due to visit a specialist on Tuesday where a clearer picture of the length of time he faces on the sidelines may emerge and a recovery programme will be discussed.
Terriers boss Lee Clark admits it is a setback to lose one of his key men for such an extended period of time.
Clark told the club's official website: "It's a clean break quite high up the arm and we've been told Gary is out for a minimum of six weeks.
"He was able to come back home by car on Saturday night, but he will have to see a specialist to determine what type of treatment is needed.
"It's a big blow for him and the club, because Gary has been playing well on a consistent basis and did well in the short time he was on the pitch on Saturday."
