Stuart Hogg may have lost sight if he stayed with the British & Irish Lions

Warren Gatland has revealed medics warned Stuart Hogg could have risked losing his sight if he suffered another bang on top of his cheek injury.

Scotland full-back Hogg will miss the rest of the British and Irish Lions tour after sustaining a “facial bone fracture” during Saturday’s 12-3 win over the Crusaders.

Hogg collided unwittingly with Conor Murray’s elbow as the Ireland scrum-half sought to let the Glasgow star launch a counter-attack in the first half of the Crusaders clash.

The Lions hope they will not need to call up a replacement, but head coach Gatland admitted they canvassed four specialists before ruling Hogg out of the rest of the New Zealand tour.

“It was just a freak accident,” Gatland told Sky Sports.

“He’s absolutely gutted. We’re feeling for him.

“We saw about four different specialists: one of them said he’d be alright and another said it’s potentially serious and that he could lose his sight if he plays.

“We told him it was only a game of rugby and he understood that.”

Without Hogg the Lions suffered their second loss on the tour, going down 23-22 to the Highlanders.
