The ruling puts the club in a difficult position as they have already filled their allocation of five visa-players and two marquees for this season. The club faces the prospect of having to manoeuvre one of their five foreign players outside of the squad or keep Keogh on hold as an injury replacement player to field him in the A-League.

Keogh has been signed for the remainder of the season and the club is also hoping to extend the player's second spell at nib Stadium until the end of the 2017/18 A-League season.

The 29-year-old striker had his contract terminated with the club in July in the wake of salary cap breaches that wrecked the Glory's hopes of winning a first A-League title.

The Glory were found guilty by the FFA of paying Keogh $200,000 through family members which was not reported in the salary cap. After the club was forced to release him from the final two years of his contract, Keogh signed a lucrative deal with Thai club Ratchaburi, before seeking a return to Perth, where his family is understood to be living.
