Carlos Corberán has confirmed attacker Jeremy Sarmiento will be sidelined for around four weeks after suffering a quadriceps injury.
The Ecuador international, on loan from Brighton and Hove Albion for the 2023/24 campaign, missed Tuesday night's 1-0 win against Sheffield Wednesday at The Hawthorns.
The boss said: "The risk with Jeremy to play the game, whenever he is playing more minutes, always there is a risk because he's a player who hasn't had the habit to play games.
"He had some pain in the quadriceps. He was playing some minutes at the end of the Preston game and he felt pain in the muscle, in the left quadricep.
"With this pain, he was receiving treatment on Sunday and when the doctors checked - when the pain was there and didn't disappear, they made a scan - yesterday, it showed an injury. It is going to keep him apart from the group for four weeks. It's difficult.
"It's something that I have been very, very conscious about, when I've given minutes to him. He had some history of injuries, plus no habit to play games.
"It's difficult, because when I heard yesterday that he would be injured for four weeks, it's going to affect you. It doesn't mean we don't have solutions, but I never want to lose any player."
