Currently in Canada, Jones was due to start for Wales in Toronto on Saturday but will instead be heading for New Zealand. Ryan will provide cover for the injured Simon Taylor.
Sir Clive Woodward, Head Coach of the British & Irish Lions said: “I offer my congratulations to Ryan, he has had a good season with Wales, he has made an impact on the international scene very quickly and we look forward to him joining us next week.
“Obviously Simon’s discomfort following our last training session is causing us some concern but we are still hopeful that he will be able to work through it and contend for a test spot but in the meantime we are adding Ryan Jones to the touring party.”
