The Spaniard suffered an engine failure on his first lap in practice at the Spanish Grand Prix, the latest in a series of problems for Honda in 2017.
It is reported that McLaren owner Mansour Ojjeh and boss Zak Brown met with Mercedes chief Toto Wolff after that disastrous session in the Mercedes motor home, where they discussed a Mercedes engine deal for 2018.
"Yes, we met," Wolff confirmed, but did not divulge the details of the meeting.
However, as per Auto Bild, a plan is being devised to save face for struggling Honda, who will reportedly announce a grand plan to work exclusively with Sauber in 2018 and beyond.
"We are not doing anything for Honda. That is the current status quo," Wolff said.
"So unless that situation changes, I don't want to contribute to rumours out there that I think are damaging for Honda. We'll see what happens," he added.
