LONDON (AP) — Crystal Palace was fined by the English Premier League on Monday following allegations the team received information about the lineup of opponent Cardiff before their game in April.

The Premier League's board upheld a complaint by Cardiff about "the conduct of a Crystal Palace official," finding that Palace had breached a rule that says teams "shall behave towards each other club and the league with the utmost good faith."

Cardiff lost the match 3-0 at home on April 5. The Welsh club was relegated from the Premier League the following month.

The Premier League didn't disclose the size of the fine but said it does not exceed 25,000 pounds ($42,000). The name of the Palace official was not revealed.

Palace sporting director Iain Moody, who was fired by Cardiff in October, denied at the time of the complaint any allegations of spying.
