Andy Murray's doubles partner Feliciano Lopez has been named in a police probe amid allegations of match-fixing at Wimbledon, according to reports in Spain.
Former world No.1 Murray is making his comeback after hip surgery alongside Spanish veteran Lopez in the doubles at Queen's Club this week.
Reports have named 37-year-old Lopez and his Spanish doubles partner Marc Lopez, 36, in a wider investigation into corruption in sport.
It is understood former world No.9 Feliciano Lopez, unavailable for comment on Tuesday as his scheduled singles match against Marton Fucsovics was rained off, strenuously denies any wrongdoing and is taking legal advice.
Marc Lopez strongly denied the allegations in Spanish newspaper AS, saying: "We have nothing to do with it, they have no right to dirty our names like that."
Murray's representatives are also aware of the claims.
According to Spanish newspaper El Confidencial, the investigation into alleged match-fixing in football involving former La Liga players Raul Bravo and Carlos Aranda has now extended to tennis, and involves a match featuring the Lopezes at Wimbledon in 2017.
In the first-round match against Australians Matt Reid and John-Patrick Smith, the Spaniards won the first set but lost the match 3-6 7-6 (7-2) 6-2 6-4.
According to the report, investigators conducting 'Operation Oikos' listened in to Aranda's phone and heard him tell the person he was speaking to that the Lopezes would lose.
However, that does not imply any wrongdoing on the part of the Spanish pair, only that information was passed on about the match.
Feliciano Lopez had retired in the fourth set of his singles match at the All England club through injury a day earlier and received treatment during the doubles match.
The Tennis Integrity Unit said in a statement: "The TIU is aware of the allegations reported but in keeping with its policy of operational confidentiality will not be making any comment on the matter."
