Week 2 of Wimbledon starts with the busiest day in Grand Slam tennis, with all 16 men's and women's fourth-round matches on Monday's schedule.

After rain delays forced organizers to schedule matches on the middle Sunday for only the fourth time in history, the tournament is back on track going into the second week.

Seven-time men's champion Roger Federer is scheduled first on Centre Court, facing 29th-ranked Steve Johnson.

Six-time women's winner Serena Williams is paired against Svetlana Kuznetsova in the next match on Centre Court, followed by No. 2 Andy Murray against Nick Kyrgios.

Missing from the schedule is No. 1 Novak Djokovic, whose 30-match Grand Slam-winning streak was snapped by Sam Querrey in the third round on Saturday.
