Blackburn Rovers say the process of signing Nottingham Forest midfielder Lewis O’Brien is still ongoing.
The Ewood Park club are hoping to secure the 24-year-old on a loan deal for the rest of the season.
However, there was an issue regarding the timing of the deal on deadline day in January.
Rovers said in a statement: “Blackburn Rovers can provide the following update to supporters regarding its ongoing attempts to find a positive resolution to its January transfer activity when two registration applications (O’Brien and Ethan Brierley) were rejected following the closure of the transfer window.
“In the best interests of the players involved, the club has tried to conclude this matter as quickly as possible via an independent arbitrator, but due to the complexities involved, the confidential legal process is ongoing.
“Throughout this process, Rovers has been in regular dialogue with the players’ clubs, Nottingham Forest and Rochdale AFC, along with the players’ representatives.
“Rovers and the EFL will continue to work on finalising their respective legal submissions over the coming days in order to get this matter concluded at the earliest opportunity.
“The club wishes to thank its supporters, along with all interested parties, for their patience and cooperation during this period.”
