The 32-year-old, five-times a victor of the singles at the prestigious Wimbledon warm-up event, delighted a large evening centre court crowd with some fluent shot-making as he and Spanish veteran Lopez beat top seeds Juan Sebastian Cabal and Robert Farah 7-6 (5) 6-3.
Murray said afterwards he would be playing doubles at Wimbledon with Frenchman Pierre-Hugues Herbert.
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".
"The court can get quite slippery and when I was outside the doubles alley I felt a bit uncomfortable at times", he said.
But Murray claimed: "I'm really not bothered about it".
"You know, Feli played extremely well, too, which helped".
"I was a bit slow at the beginning but got better as the match went along. I'll try to keep progressing from here, but I'm just happy being back on the court".
"This felt different to last year, because last year when I came in and played, I mean, my hip felt very average, like, I was still pretty uncomfortable and I had done a lot of training".
"Obviously I don't know how is he going to feel".
Lopez added that he went into that game in question struggling with a foot injury which had forced him to retire during his first round match against Adrian Mannarino.
That is because Lopez's singles match against Marton Fucsovics was one of those which fell foul of Tuesday's weather, and the Spaniard is now first on Court One at noon.
But when he did step out onto the grass, he looked a different player to the one that was limping around for the best part of two years. And the other time was playing in the golf club championships at Wentworth last week - especially when I handed in my card having shot triple figures!
Two first-round matches have been held back until Thursday, those between Nick Kyrgios and Roberto Carballes Baena, and Grigor Dimitrov and Felix Auger-Aliassime.
Barty saw off a bright start from Croatia's Donna Vekic in her first match since lifting a first grand slam title to win 6-3, 6-4 and set up a second round meeting with American Jennifer Brady. "I don't anticipate it would be much longer than that". I thought some of the calls were outrageous today. He gave me a point at a pretty crucial time, and I gave him a point at a pretty crucial time.
For some, it affects the way they think, but it doesn't affect me in that way.
They have seen everything I've been through and I think they were a bit apprehensive and a bit nervous, even though they didn't want to show it. I had a conversation with them in Miami after I got fined again for their mistake.
