According to a loudening rumour on the microblogging website Twitter, McLaren is poised to announce a new member of its technical team.
The rumour goes that the new appointment is Sam Michael, Williams' departing technical director.
The 40-year-old Australian said earlier this year he would "clearly be in Formula One next year" but said he "can't talk about" the details.
His last Grand Prix on the Williams pitwall, which he joined from Jordan in 2011, will be Korea next month.
Michael was earlier linked with possible moves to Force India, Mercedes and Ferrari.
"Everything is open for the future," he said in late July.
