TOWN striker Robbie Simpson is again ruled out by injury when Leyton Orient visit the Galpharm tomorrow.
The 24-year-old hasn't played since the defeat at Colchester on October 3 because of a thigh injury.
Simpson has missed the last three games and manager Lee Clark explained: "It's incredibly frustrating for Robbie.
"He has come here determined to play his part and show what he can do in regular league football, but it's been a bit of an 'in and out' situation for him.
"He has found it frustrating, especially in the last few days when he's put the injury to the test, because he's just not quite ready.
"If he played this week it could set him back for much longer, so it's not worth the risk. He can do three quarters of the work, it's just with the long kicking that he's struggling at the moment."
