Paul Dickov admitted his side were ‘shell-shocked’ following the late omissions of injured duo Rob Jones and Theo Robinson against Brighton.
Both were expected to start in the Championship clashbut were forced to withdraw due to injuries.
Striker Robinson was unable to shake off a hamstring problem as skipper Jones experienced a neck injury which later led to a loss of feeling in his arm during the matchday warm-up.
The centre back, who was sent for a scan the next day, was replaced by Luke McCullough who had just minutes to prepare for a first team start before kick-off in a game which marked the former Manchester United defender’s first start since his free transfer to Rovers.
The match also saw a first start for loan signing Yun Suk-Young who slotted in at left-back as Paul Quinn dropped to the bench.
Dean Furman also made way for David Cotterill as the Doncaster boss rang the changes.
“We were a little bit shell shocked about the loss of Theo and Rob,” said Dickov following the 3-1 Seagulls defeat.
“Both were down to start the game.
“Theo had a hamstring problem in the morning and Rob’s headed the ball and felt something go in the back of his neck and has lost feeling in his arm.
“It was a big blow. They are both big players for us.”
Dickov reflected:“First half maybe we were off the pace because of the circumstances [Jones and Robinson late injuries].
“Luke McCullough was told he was starting four minutes before kick-off. He did well and grew into the game.”
The Scotsman went on: “We were much better second half, that is how I want us to play.
“We played with a better level of intensity, put more balls into the box and we deservedly got back into the game.
“The second goal was very scrappy. The ball has bounced around and [Leroy] Lita has reacted first and put the ball in the back of the net.
“The other two goals, we can’t do a lot about because they were both wonderful strikes.”
