Holders Arsenal's 14-match winning run in the FA Cup ground to a halt in a dreary 0-0 draw at home to Championship leaders Hull City in the fifth round at Emirates Stadium on Saturday.
The first of eight ties spread over three days was less than gripping as Hull hung on for a replay both sides could do without as they chase their respective priorities.
There were goals elsewhere, though, as second-tier strugglers Reading shocked Premier League West Bromwich Albion 3-1 and Watford saw off Leeds United 1-0.
Bournemouth host Everton later on Saturday in an all top-flight clash while on Sunday the standout tie of the round is Chelsea v Manchester City.
With one eye on Tuesday's Champions League last 16 first leg at home to Barcelona, Arsenal made nine changes from the side that beat Premier League leaders Leicester City last week.
