Sheffield United striker Oli McBurnie will miss the rest of the season with a foot fracture.
It follows fellow striker Billy Sharp being ruled out for the remainder of the season on Wednesday after having surgery on a thigh injury.
“Oli is out for the season as well,” said interim boss Paul Heckingbottom.
“He’s got a stress fracture in his fifth metatarsal so we’ve lost two forwards, which isn’t positive.”
McBurnie, who joined the Blades from Swansea in 2019, has scored one goal in 23 league appearances this season.
Sheffield United are bottom of the Premier League table, 18 points from safety, with seven games left.
