Gillingham boss Andy Hessenthaler has an injury doubt over Curtis Weston for the home clash with Barnet.
The creative midfielder had been struggling with a knee injury ahead of last weekend's 1-1 draw with Morecambe but declared himself fit to start the game.
However, the 24-year-old limped out of the game after 69 minutes and is now a major doubt to face the Bees.
Striker Dennis Oli remains sidelined with a recurring hamstring problem that has blighted his season, while Stefan Payne also misses out again with a knock.
With attacking options limited, Hessenthaler has hinted that Luke Rooney could take up an attacking role.
He told the club's official website: "Fortunately we have Luke Rooney who is, without doubt, a forward thinking player, he is attack-minded, he makes things happen, and I thought he did really well when he came on against Morecambe."
Barnet welcome Sam Walker and Mark Hughes back from suspension.
On-loan Chelsea goalkeeper Walker served a one-match ban at Bury last week following his red card against Crewe and midfielder Hughes was suspended for two games after a 10th booking of the season.
Walker is set to get the nod ahead of Liam O'Brien while Hughes could also have good reason to expect a recall after Lawrie Sanchez joined the Underhill staff this week - Hughes was capped twice for Northern Ireland while Sanchez was in charge of the national side.
On-loan Southampton midfielder Anthony Pulis is fit after an Achilles injury and forwards Steve Kabba and Izale McLeod are expected to shake off minor knocks.
