Stuart Hogg will be sidelined for the remainder of the British and Irish Lions' tour of New Zealand after succumbing to a facial bone fracture.
Hogg sustained the injury during Saturday's 12-3 win over Super Rugby leaders Crusaders when he collided with team-mate Conor Murray.
The 24-year-old underwent tests following the match and the Lions confirmed on Tuesday that he will play no further part in the tour.
Hogg will return to Scotland for further treatment, while no replacement will be called up.
"I'm gutted to be leaving to be leaving the Tour at this stage," Hogg said as the Lions prepared to face Highlanders In Dunedin on Tuesday.
"It is an honour to have been involved in a second British & Irish Lions tour and I have hugely enjoyed my time with the squad and I'm very excited about the potential of this group.
"I'm disappointed to be leaving in this way but wish all the squad the best in the coming weeks and will be cheering them on from home."
Head coach Warren Gatland added: "It is hugely disappointing for Stuart to have to return home early and for us to lose one of our touring party.
"Stuart has been a key member of our squad on and off the field and it is disappointing to see injury cut short his time with us in New Zealand.
"We all wish him the best with his recovery and we look forward to seeing him back in action in the future."
