For the third tour in succession, the British and Irish Lions’ Test series comes down to a final-match decider.
South Africa won Saturday’s second Test to level the series at 1-1 and leave everything on the line in Cape Town this weekend.
Here, the PA news agency looks at the tourists’ record in previous series deciders.
2017 – New Zealand 15 Lions 15
Having lost the opening Test despite Sean O’Brien’s breathtaking team try, the Lions hit back to win the second 24-21 on Owen Farrell’s crucial late penalty.
That set up a winner-takes-all clash in Auckland – only for the spoils to be shared, as Farrell’s fourth penalty to go with a long-range Elliot Daly effort left the scores tied at 15-15. A late penalty seemingly awarded to the All Blacks was ultimately deemed a scrum instead and the Lions held on.
2013 – Australia 16 Lions 41
The first two Tests were as tight as could be, Australia’s Kurtley Beale slipping to miss a potential match-winning penalty in the first while Leigh Halfpenny was off target in the second.
The third, though, saw Halfpenny inspire one of the all-time great Lions performances in a 41-16 win. The Wales full-back set up tries for Johnny Sexton and George North and kicked a Lions-record 21 points in the Test and 49 on the tour.
2001 – Australia 29 Lions 23
The 2005 and 2009 series against New Zealand and South Africa respectively were already lost going into the final Test, but back in 2001 it was 1-1 after the Lions won the opener 29-13 but were beaten 35-14 in the second Test.
Tries from Jason Robinson and Jonny Wilkinson gave Graham Henry’s side hope in the decider and the scores were tied with 12 minutes left, but Matt Burke kicked two Australia penalties and Justin Harrison’s lineout steal denied the Lions the chance of a match-winning try and sealed a 29-23 success for the Wallabies.
That is the last time a team came from one Test behind to win a Lions series, the feat South Africa will be looking to match on Saturday.
1993 – New Zealand 30 Lions 13
A 2-1 win over South Africa in 1997 was wrapped up before the third Test but 1993 had been decided by the smallest of margins. Gavin Hastings’ sixth penalty appeared to have given the Lions victory in the opening game only for Grant Fox to hit back in the last minute – and the 20-18 win would prove crucial.
The Lions impressively won the second Test 20-7, Rory Underwood with a memorable try, and led the decider 10-0 only for the All Blacks to hit back in style for a 30-13 success after tries from Frank Bunce, Sean Fitzpatrick and Jon Preston.
1989 – Australia 18 Lions 19
Recovering from a 30-12 opening loss, the Lions won the second Test 19-12 thanks to late tries from Hastings and Jeremy Guscott.
Ieuan Evans took advantage of rival wing David Campese’s error to score what proved the crucial try in a 19-18 decider, with Hastings slotting five penalties.
Of the 22 Lions series across 19 previous tours since the second world war, exactly half have gone into the final game with the series result still on the line.
That includes three four-Test series and three two-Test encounters in which the team trailing had the chance to level the series, as well as the aforementioned five tours since 1989 with the now-established three-Test format.
The Lions have won five, drawn two and lost four of those deciders, with 1971’s draw against New Zealand earning a 2-1 series win. The All Blacks won in 1977 to clinch a 3-1 win, meaning South Africa’s win in the 1955 decider led to the only drawn series prior to 2017.
The three two-Test series were all against Australia on split tours headlined by New Zealand, with the Lions running out 2-0 winners on each occasion.
