Sheffield United new boy Simon Walton's career with the club looks to be over before it has even started.
The well-travelled 22-year-old joined the Blades on a season-long loan from Plymouth earlier this month, but suffered cruciate knee ligament damage in a friendly against Mansfield on Saturday meaning he is unlikely to play at all this season.
"It is a tragedy for the lad because he was going to give this chance his best shot," manager Kevin Blackwell told United's 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."
