Ipswich Town loanee Brandon Williams has 'suffered a set-back in his recovery', manager Kieran McKenna has revealed.

The 23-year-old full-back returned to parent club Manchester United in January for 'medical assessment' following a series of repeated illnesses and 'knocks'.

On February 2, McKenna said he expected Williams to return to the club 'in 10-14 days'. That was three weeks ago.

"We were hoping that would be the timescale, but he's a had a set-back in his recovery," said the Blues boss.

"He's still at United, he's not training yet. We're not sure how long the set-back is going to take, but he's not even on the grass with them yet. So he's still a little way away."

Town take on Birmingham City in a Championship clash at Portman Road tomorrow. Asked for injury updates following Tuesday night's 4-3 home win against Rotherham, McKenna said: "I think we've come through it pretty well.

"Kieffer (Moore) got a knock on his knee, but he's been able to train today.

"Jeremy (Sarmiento) had a scan on his hamstring, thankfully that was just tightness and there was no strain - he was able to do a bit of the session today and there's a possibility he could be involved tomorrow.

"Harry (Clarke) had a pretty severe dead leg, so he's been very inhibited. We're going to have to leave that decision until tomorrow to see what his involvement might be able to be.

"Wes (Burns) landed on his shoulder, but there's no issue.

"Of course it's been a busy run of games and that did show in bits of the game on Tuesday night, but everyone today seemed in a pretty good place and I'm sure by the time kick-off comes around, with a packed out Portman Road, the energy levels will be really good."

Asked for an update on long-term striker absentee George Hirst, who underwent hamstring surgery last month, McKenna replied: "He's progressing as planned. He's working in the gym, he's not on the grass yet and he's still on course to hopefully be be fit in and around the back end of the season."

Janoi Donacien (groin) and Jack Taylor (quad) also remain sidelined for the Blues.
