Millwall defender Byron Webster has suffered a serious knee injury.

The 30-year-old has ruptured a cruciate ligament that will see him sidelined for most of the season.

Webster, who is in the final year of his Lions contract, played a pivotal role in the club’s strong start to the Championship campaign.

And it will come as a huge blow to Millwall boss Neil Harris, who has Jake Cooper and Tony Craig ready to fill the void.

He said: “This is a major disappointment, first and foremost for Byron, whose form at the start of this season has been outstanding.

“As well, it is of course a disappointment for the group. However, we will grow stronger because of it. Others will now have to step up in Byron's place and take their opportunity.

“We don't want to put a definitive timescale on his recovery but it will be long-term.

“Seeing Byron back before the end of the season would be a huge bonus.”
