New signing Simon Walton's career with Sheffield United has stalled before the new season has even begun.
The 22-year-old, who arrived at Bramall Lane from Plymouth on a season-long loan earlier this month, has sustained cruciate knee ligament damage and is unlikely to play at all in the coming campaign.
Blades manager Kevin Blackwell admits the injury, which Walton sustained during Saturday's friendly against Mansfield, is disappointing for the young midfielder.
"It is a tragedy for the lad because he was going to give this chance his best shot," Blackwell told the Blades' official website.
"He won't play for us now because his loan will be up by the time he recovers. We are now talking to Plymouth about where Simon will do his rehab."
