Serena Williams plans to make her return to singles competition via a wild-card entry at Wimbledon, where matches begin on Monday. Williams is a seven-time champion in singles at the All England Club, part of her collection of 23 career Grand Slam titles, a record in the professional era (which dates to 1968). The 40-year-old American won two matches in doubles alongside Ons Jabeur this week at a grass-court tournament in Eastbourne; before that, Williams had not played any sort of official contest anywhere since injuring her right leg and needing to stop during the first set of her first-round match on Centre Court at Wimbledon a year ago. This is not the first comeback from a significant absence for Williams. Here is a look at other times she missed two or more consecutive Grand Slam tournaments since making her major championship debut at the 1998 Australian Open:

2003-04

Why: Left knee surgery to repair a partial tear in the quadriceps tendon

Grand Slam Tournaments Missed: 2 — 2003 U.S. Open and 2004 Australian Open

Age at Return: 22

How Many Majors Until Reaching a Final After Return: 2 (Runner-up at Wimbledon in 2004)

What Williams Said Then: “I’m going to be a better player, for sure, when I come back. My knee is going to be better than it’s been ever in my career, which is really exciting, and ... I’m going to be mentally relaxed. I’m going to be stronger, and I’m going to be angry.”
