Blackburn's loan duo Alex Baptiste and Jay Spearing are both ineligible to play against their parent club on Wednesday night, with the terms of their respective deals from the Macron Stadium to Ewood Park preventing them appearing.
Centre-half Baptiste has been a mainstay of the Blackburn team this season, making 25 appearances and forging a dependable partnership with Matt Kilgallon in the absence of the injured Shane Duffy.
Kilgallon and Baptiste were at the heart of the intense rearguard action which kept Liverpool at bay in Sunday's goalless FA Cup quarter-final encounter. Having also kept the first clean sheet achieved by any club this season at Bournemouth's Goldsands Stadium in a recent 0-0 draw, Baptiste is likely to be sorely missed by Gary Bowyer's men.
Ex-Liverpool trainee Jay Spearing made a surprise loan move across Lancashire in January having made 21 appearances for Bolton in the first half of the campaign. Spearing has so far started seven games for the Ewood Park club but is ineligible for the FA Cup having played for Bolton, ironically against Liverpool, in the fourth round.
For their part, Bolton have also been active in the loan market in recent days, with the arrival of much-travelled midfielder Giles Coke from Sheffield Wednesday and central defender Paddy McCarthy from Crystal Palace, both of whom can line up for the Trotters on Wednesday night. Neil Lennon's men remain 10 points clear of the relegation places in the Sky Bet Championship, but still need the points to secure their safety.
The loan men will help to cover the absences through injury of midfielder Zach Clough and defenders Kevin McNaughton - himself a loanee from Cardiff City - and David Wheater.
