The Tennis Integrity Unit has announced that a match at this year's Wimbledon is being investigated for possible match-fixing.
One of the 96 alerts received by the TIU between July and September related to a match at the All England Club.
The match in question has not been disclosed by the investigators, who receive information of suspicious betting patterns from regulators and betting organisations.
A statement from the TIU read: "Historically, Grand Slams receive very few match alerts and in keeping with that record, only two were received during the period; one at Wimbledon, the other at the US Open. Both are the subject of routine, confidential investigation by the TIU.
"It is important to appreciate that an alert on its own is not evidence of match-fixing."
