Venus Williams beaten in Wimbledon first round by Elina Svitolina
The American, appearing at the championships for a record 24th time, retains the easy power that once made her the queen of Centre Court but went down 6-4, 6-3.
Former world number one Williams, whose last Wimbledon title came in 2008 against sister Serena, won the opening two games - but she looked in serious trouble in the next as her bandaged right knee buckled under her while she moved to intercept a volley.
The Centre Court crowd winced as she crumpled to the turf, but after staggering back to her chair and receiving treatment the old warrior spirit kicked in and she battled on.
Svitolina, who at least was born when Venus first appeared at Wimbledon, unlike 53 players in the women's draw, won four games in a row and took the opening set despite a fierce struggle to hold serve at 5-4.
Williams had more treatment before the start of set two, but dropped serve immediately with a forehand into the net.
The crowd offered plenty of vocal encouragement, one fan shouting "You've still got it, Venus", as she fought to extend the 355th Grand Slam singles match of her career - a total surpassed only by her sister Serena (423).
But former world number three Svitolina, who enjoyed a fairytale comeback from maternity leave by reaching the French Open quarter-finals last month, was ultimately too sharp as she moved into a 5-1 lead.
But Williams, who also won the title in 2000, 2001, 2005 and 2007, was not going to go down without a fight, unleashing some thunderous strokes to claw back two games.
Svitolina got the job done though and, as the evening sunshine turned to shade, Williams walked off beaten, waving what might have been a final farewell to the crowd.
