Clarets defender Danny Lafferty played the full 90 minutes for Rotherham United as they drew 1-1 with Fulham in their last Sky Bet Championship encounter.
Millers striker Matt Derbyshire continued his fine form, opening the scoring before Ross McCormack pegged them back.
Steve Evans side’s recent form has allayed fears of relegation back to Sky Bet League One, but rumours of a point’s deduction for fielding an ineligible player may deepen concerns in South Yorkshire.
Elsewhere, Alex Cisak played the full 90 minutes in the 0-1 defeat to Doncaster Rovers in midweek, with fellow Claret Luke O’Neill an unused substitute.
More recently, Cisak again completed 90 minutes but it was a day to forget as the O’s lost 6-1 to promotion-chasers MK Dons.
The O’s are now 21st in Sky Bet League One as they look to avoid the drop going into the final throes of the campaign.
Jason Gilchrist was an unused sub in the 1-1 draw with Hartlepool United away from home as Marlon Harewood late leveller kept Hartlepool's survival hopes alive.
The young forward was also named amongst the subs for the 2-2 draw with Stevenage but didn’t come on.
In the Vanarama Conference, Steven Hewitt played 90 minutes against Grimsby in a 2-2 draw on Saturday, meaning Southport’s fight for survival will go right to the wire.
