Mack Hansen has emerged as a major doubt for the British and Irish Lions' first Test against Australia as he continues to struggle with a foot injury.

Hansen sustained the injury in the Lions' 48-0 thumping of an AUNZ Invitational side last Saturday and was not involved in their training session on Tuesday.

Mixed messaging has emerged this week over whether the Ireland wing will be available for Saturday's Test, with assistant coach John Dalziel saying on Monday that he was fine.

However, Richard Wigglesworth, another assistant coach, said on Tuesday that he had suffered an injury and noted that while it was not a major concern, anyone who did not participate in Tuesday's session was classed as a "doubt".

Blair Kinghorn is also struggling to prove his fitness, having suffered a knee injury against the ACT Brumbies on July 9.

"We'll have to see [on Wednesday] what Blair looks like," Wigglesworth said.

"He hasn't trained fully with the squad, but he's been on his feet, so we'll know a bit more in the next 24 hours whether we can get him on the field."

Wigglesworth revealed the Lions have already picked their team for the series opener – subject to any late changes – with the players set to be informed on Wednesday.
