Ben Smith ruled out of Lions series

Ben Smith has been ruled out of the remainder of the British and Irish Lions Tour after suffering a concussion in the first Test.

While results from concussion protocol testing still aren't in, All Blacks management made the call to rule the 31-year-old out of both remaining Tests.

Coach Steve Hansen noted Smith has been sidelined by concussion twice in this year's Super Rugby campaign with the Highlanders.

"We're just of the opinion that he's had a couple so let's just be a little bit conservative and not play him," Hansen said.

"Long-term concerns have been allayed but we're just going to take our time with him and get him back where we need him to be, so he's comfortable and we're comfortable."

Fellow-veteran outside back Israel Dagg has been shifted to fullback for Saturday's second Test in Wellington.
