Sheffield United boss Chris Wilder provides update on Oli Arblaster plus Joe Rothwell revelation and thoughts on Portsmouth

The Blades academy product came off at half-time in Monday night's home loss to Middlesbrough after complaining of feeling unwell in the first half.

Wilder, who is still without Jairo Riedewald, who is on track to return in time for the Sheffield Wednesday derby on Sunday week, said: "During the first half, he complained to the referee halfway through, 25-30 minutes, that he wasn't feeling too great. So he had to come off.

"He's had a couple of days off. He came back in yesterday, so we're hoping he's going to be available. Pat (Bamford) came through, okay, everybody else (from Monday) is fine."

Joe Rothwell starts the first game of a three-match ban at Fratton Park following his late dismissal for a wild challenge on Alan Browne against Boro.

Wilder added: "I think we all, every United fan - certainly me and the coaches and the players speaking to them - believed that little swinging momentum when we got ourselves back into the game would take us to at least get a draw out of it.

"But, obviously, Joe can't get away from it and I've talked to him about it. Where was your head at? He said: 'I just wanted to make a big tackle to lift the crowd'.

"Unfortunately, his timing was off and I think that might be because of not playing a lot of football as well.

"He's disappointed. He was sat in the changing room with his head in his hands, really. He understands that situation. He committed to a tackle and didn't get it right.

"But, even at the end, Japh (Japhet Tanganga) had a header, really (to equalise). Another day, it could have gone in and if we all walk out that ground with a two each, it's a good feeling. But, I'm not going to beat the boys up too much about it and we go again on Saturday."

United face a Pompey side battling for their lives at the bottom end of the Championship.

John Mousinho's side have lost just once in their past eight home league outings on the south coast and beat West Brom 3-0 last time out. They also vanquished current leaders Boro earlier this season.

Wilder commented: "It's always a challenge in Championship football.

"Both teams are after three points in an attempt to climb the table. Nothing changes in our approach. We understand the challenges that we've had over the last three games against Portsmouth.

"Going down there last season, it was a really tough place to go and get a result. It proved that on the day. We could have won it.

"We could have lost it. I believe a draw was maybe a fair result. It was definitely a tight game at home.

"I think we nicked that one. The (Portsmouth) sending off maybe a played apart in the home game this year. It was running out comfortably on the night.

"I don't think anything will change. I don't think anything changes in terms of any game in the Championship.

"Yet again you'll look through the fixture list. I think everybody thought it was a foregone conclusion that we'd roll Oxford over. They go to Coventry and get a draw. They're top of the division.

"This is the challenge of Championship football. Wherever you go."
