PAUL RACHUBKA was left out of Town's training session today to receive further treatment on his troublesome back.
The 23-year-old goalkeeper was forced to pull out of Saturday's 2-1 win at Peterborough after suffering pain during the warm-up.
Phil Senior took his place at the last minute, but Rachubka is hoping to be back at the Galpharm on Saturday as Town aim to make it five wins on the trot against Doncaster Rovers.
But manager Peter Jackson is taking no risks with Rachubka's fitness.
"Rabs was in for treatment yesterday, he will be monitored over the next couple of days and we'll see how he goes," said Jackson today.
"We will obviously leave it as late as we can and, hopefully, he will keep responding to treatment.
"It wasn't until about 2.15 on Saturday, when he was doing the warm-up with our physio, Lee Martin, that we realised Rabs was still having a major problem.
"We knew he'd been bothered through the week, but it seemed as though he would be okay.
"When he came to me before the game and said he was really struggling, I told him there was no way we could risk him playing and immediately made the switch with the officials.
"I then had to drag Danny Adams out of the stand to go on the bench."
Rachubka (pictured) admitted he was gutted to have missed a first-team game through injury for the first time in his career.
"I had been struggling with a jarred back and lower back pain all last week, having managed to get through the game against Sheffield Wednesday," he said.
"It obviously needs to get a lot better than it was, but we should know a lot more about it by later in the week."
Rachubka will attempt to join the squad training session on Thursday.
