March 12 (REUTERS) - An injury to Harry Kane marred Tottenham Hotspur's party as they marked their last FA Cup tie at their White Hart Lane ground with a 6-0 thrashing of third-tier Millwall to book their place in the semi-finals on Sunday.

England international Kane, the Premier League's joint top scorer, had to hobble off after falling awkwardly and suffering an ankle injury in a sixth minute challenge during their quarter-final match.

Yet his absence was not missed on the day as Son Heung Min hammered a brilliant hat-trick and Kane's replacement, Christian Eriksen also scored a beauty before Dele Alli and substitute Vincent Janssen got in on the act.

It all made for an emotional occasion at Spurs' storied 118-year-old ground which they will leave at the end of the season.
