The Court of Arbitration for Sport has rejected an attempt by Spanish club Malaga to overturn a UEFA ban from next season's Europa League over previously unpaid debts.

At a hearing last Tuesday, Malaga challenged UEFA's decision in December to ban the Qatari-owned club from one European competition for missed payments of players' wages and social taxes.

Clubs must pay football and tax debts to retain a license from their national association to play in UEFA competitions.

Malaga, which reached the Champions League quarterfinals under coach Manuel Pellegrini, then finished sixth in the Spanish league to earn a Europa League berth.

But with the CAS appeal thrown out, Malaga is set to be replaced in Europe's second-tier club competition by Sevilla.

UEFA's club finance judicial body also fined Malaga 300,000 euros ($398,000).

"The club will comply fully with the penalty imposed by UEFA by not participating in the next edition of the Europa League and paying a financial sanction," Malaga said in a statement after the CAS announcement on Tuesday.
