Grant McCann has confirmed that midfielder Tom Huddlestone will miss the next four to six weeks through injury.
The 34-year-old returned to the starting line-up against Peterborough United, before he was forced off with a hamstring injury after 29 minutes.
McCann said: “It’s a reoccurrence of the hamstring injury in a different area.
“None of us could foresee what was going to happen and how this was going to come about. Tom has felt good over the last 10 to 12 days, so again it’s a kick in the teeth for us.
“We’ll see how he recovers but we’re probably looking at a timescale of four to six weeks. It gives him another opportunity to go and work physically in the gym.”
Richie Smallwood replaced Huddlestone against Peterborough, and McCann says it’s good to have two midfielders of their experience in the squad.
“We’ve got two very experienced central midfielders in Tom and Richie,” McCann added.
“They are both very good at what they do. When they’ve played, they’ve both been in good form this season. When we’ve got three-game weeks, it’s important that we share the load a little bit.
“We’ve got young and energetic midfield players in and around them. They both add different qualities to our team. Their know-how and experience is vital in our team. It’s disappointing news for us about Tom, but this is football. You pick up knocks and niggles all the time and it’s an opportunity for someone else now.”
Aside from Huddlestone, McCann confirmed the majority of the squad got through the game in midweek without picking up any further knocks.
“I think everyone else is fine,” McCann said.
“We had a little bit of an issue with Nathan Baxter (calf). We’ll see him again today and see whether he can make the game on Saturday. It’s just a niggle that he’s had for a while but it's nothing serious.
“If it’s deemed not suitable for him to train today, then he may miss one game, but we’ll see what the physios think of him this morning.”
