The EFL has decided not to punish Huddersfield Town after they fielded an 'under-strength' team for their Championship fixture with Birmingham City.

With a playoff spot already secured, Terriers boss David Wagner made 10 alterations to his starting lineup for the match at St Andrew's, which Birmingham went on to win 2-0.

Blackburn Rovers were able to argue that they were directly impacted by the result and they were subsequently relegated from the second tier, but the EFL has acknowledged that the ruling, and the wording of 'full-strength', was open to interpretation.

A statement read: "At its meeting on Thursday May 11 2017, the EFL Board fully considered the matter of whether there had been a breach of EFL Regulation 24 by Huddersfield Town in their recent Sky Bet Championship match with Birmingham City. The regulation states that Clubs must play their 'full strength' side in all fixtures unless some satisfactory reason is given.

"The Board closely examined the observations put forward by the Club and a decision was taken to not bring a disciplinary charge against the Club. The EFL Board accepts that Clubs' primary obligation will always be to themselves, however, there is a significant concern that by adopting this approach it could have a detrimental effect on the competitiveness and reputation of the League competition.

"Having considered all matters, there is no doubt in the Board's mind that Huddersfield Town could have fielded a 'stronger' team, but in the absence of a full and detailed definition of what constitutes 'full strength', there was sufficient scope for the Club to make a significant number of changes to its starting lineup.

"As a result of Huddersfield's interpretation of the current regulation, the Board has requested the EFL Executive to consider amendments to ensure that the actions of any individual Club cannot be seen to negatively impact the credibility and public perception of the competition."

Blackburn finished two points below Birmingham in the league table`.
