Chester FC are sweating on the fitness of defender Ben Heneghan for Tuesday's vital clash with relegation rivals Torquay United.
Along with top scorer Ross Hannah and teenager Sam Hughes, the 22-year-old has been one of the few shining lights in a difficult campaign for the club.
Heneghan had to be replaced 52 minutes into the 2-2 draw with Boreham Wood on Saturday after twisting his knee making a clearance and the England C international looks doubtful for the trip to Plainmoor in a game the Blues cannot afford to lose.
He will be assessed at training this morning and manager Steve Burr will be hoping the damage is not as serious as first feared.
"Ben twisted his knee in a tackle so we'll assess it but you know there's something wrong with Ben when he doesn't carry on," said Burr following the draw with Boreham Wood.
"It was impossible for him to carry on and that was a blow that was dealt to us but we'll just have to assess the injury and see how he is but hopefully it's nothing too serious and we can get him back in the team for Tuesday."
Should Heneghan not be available to face Torquay, who could close to within a point of Chester with victory after a run of five wins and three draws from 10 games, then club captain Ian Sharps, who has recovered a from a hamstring strain, would be the most likely replacement.
Salford-born Heneghan has been a near ever-present for the Blues in the league this season, missing two games through suspension.
He moved to Chester in August 2014 after being released from Stoke City and has made more than 80 appearances over the past two seasons.
Heneghan's contract expires at the end of the season and, while he has not ruled out signing a new deal, his performances have attracted interest from Football League clubs with The Sun last month reporting Brighton & Hove Albion, Blackburn Rovers, Burnley and Hull City are monitoring his progress.
