Most of the Premier League big boys have safely made it through to the FA Cup fifth round.
Manchester United beat rivals Liverpool in Sunday's teatime match, while a Tammy Abraham hat-trick helped Chelsea to a 3-1 win over Luton earlier in the day.
Manchester City also beat lower-league opposition, although they were given a scare by League Two Cheltenham before eventually winning 3-1.
One club that hasn't made it is Arsenal, the current holders who lifted the trophy for a record 14th time last season. The Gunners slipped to a 1-0 defeat at Southampton.
The final non-league side, Chorley, from the National League North, are also out after losing 1-0 to Wolves on Friday evening.
