Rotherham United defender facing two months on sidelinesÂ

The Norwich loanee suffered a knee and ankle problem after a block challenge in the first half of Saturday's defeat at Wigan and will undergo surgery, understood to be on his ankle, next week.

Raggett revealed his heartbreak on Twitter, but is confident he can make a speedy recovery.

Captioning a picture of him scoring the winning goal against Millwall last month, the central defender said: 'Gutted with the injury news and needing surgery but set backs happen and I'm already looking forward to getting back stronger, better and doing more of this in a few months time.'

Boss Paul Warne said after the game that he feared the worse but this news will come as a big blow to the Millers.

Raggett, on a season-long loan from the Canaries, was beginning to establish himself in the defence alongside Richard Wood following Semi Ajayi's move into midfield.

His matchwinning header against Millwall capped off a fine individual performance and his aerial prowess had quickly become an asset in both penalty areas.

Warne has nicknamed him the 'serial killer' owing to his desire to beat anyone to the ball and said he is reminded of his former team-mate Chris Swailes, who had similar attributes.

The club will see how the 24-year-old pulls up after surgery before deciding whether to send him back to Carrow Road for rehabilitation.

Either way, Warne will definitely be without him once the Millers get back under way after the international break.

And that will give Clark Robertson the chance to kick-start his Rotherham career.

The Scot, who turned down Sunderland to join the Millers in the summer, has only started in the Carabao Cup so far and one of those games was at left-back.

He came on to replace Raggett at the DW Stadium and after doing well, now gets the opportunity of a sustained run in the side.

Warne said: 'Robbo did well when he came on and he has been more than patiently waiting for his chance.

'Without sounding a bit sick, it is next man up, the next man has to come in and perform.'
