Former Scotland international Blade Thomson has retired from rugby due to a head injury.

Thomson, who has spent the last five years with Welsh side Scarlets, issued a statement on Thursday to confirm his decision.

Scarlets boss Dwayne Peel said at a press conference on Tuesday that Thomson was out with a head problem, adding that it was a "work in progress".

However, the player has now taken the decision to hang up his boots at the age of 32.

New Zealand-born Thomson won 10 caps for Scotland, including playing at the 2019 World Cup in Japan.

In a statement released through Scarlets, Thomson said: "Myself and my family have come to this decision and I'd like to thank everyone, coaches, players, the back-room and medical staff and all the fans for their support.

"We've been made welcome from the moment we came to Llanelli. It's a special place to play and I'm proud of what I've achieved, making more than 50 appearances for the Scarlets and having the honour of representing Scotland.

"We will leave with fond memories of our time here."

Scarlets will honour Thomson with a presentation following Saturday's United Rugby Championship game against Edinburgh.
