FA Cup Round-up:Kevin Phillips served a timely reminder of his Premiership quality as West Brom twice came from behind to take Middlesbrough to an FA Cup fifth-round replay.
The former Sunderland striker returned to the north-east to snatch a 2-2 draw for the Coca-Cola Championship high-fliers via a deflection off Andrew Taylor.
It was a terrific fightback for the visitors, who conceded a sucker-punch penalty on the stroke of half-time, only moments after making it 1-1.
The result was soured by Curtis Davies' late sending off for an untidy challenge on Mark Viduka.
Boro dominated the early exchanges, with Emanuel Pogatetz having a header cleared off the line before Julio Arca headed in Stewart Downing's brilliant right-wing cross.
The Baggies looked set to go in level when Diomansy Kamara slotted the ball under Mark Schwarzer from a tight angle but Davies then fouled Ayegbeni Yakubu, who then made amends for his two spot-kick misses in the fourth-round replay against Bristol City.
Ten-man Ipswich looked set to join West Brom in the hat for the quarter-final draw before suffering late heartbreak at Watford.
With a replay beckoning, Damien Francis met Tommy Smith's low cross to send the Premiership's bottom side through. The visitors' chances of an upset were dealt a blow when George O'Callaghan was sent off on the stroke of half-time.
Making his full debut, the midfielder was given his marching orders after referee Steve Bennett deemed that he had aimed a kick at Hornets defender Danny Shittu.
Ipswich could have earlier been in front when former Fulham midfielder Sylvain Legwinski hit the bar from 25 yards.
The 10 men continued to attack and thought they had taken the lead when Dan Harding's shot hit the underside of the bar and Danny Haynes headed home the rebound only to be denied by the offside flag.
Plymouth reached the quarter-finals for the first time in 23 years thanks to a 2-0 win over Championship leaders Derby.
Kevin Gallen scored a controversial penalty and on-loan Chelsea starlet Scot Sinclair headed in a late second to send Ian Holloway's side through.
Former QPR striker Gallen also missed another penalty, while the Rams had defender Darren Moore sent off.
Gallen earned the first penalty when Dean Leacock was adjudged to have brought him down, despite there appearing to be little contact.
Derby goalkeeper Stephen Bywater got both hands to the spot-kick, turning the ball onto the post, but he was unable to prevent it creeping in.
The second penalty was more clear-cut, Moore penalised for climbing all over Krisztian Timar. Gallen stepped up again but this time Bywater kept his attempt out.
The second half saw Moore dealt a second yellow card for a tackle from behind on Gallen before Sinclair nodded in David Norris' cross to wrap up the win.
Chelsea survived an early scare before turning on the style to crush Norwich 4-0 at Stamford Bridge.
The Premiership champions were indebted to a wicked deflection to go ahead when Shaun Wright-Phillips' long-range shot deflected off a Canaries defender.
Didier Drogba scored his 26th - and easiest - goal of the season to make it 2-0 after a corner had deflected through to him.
Strikes from substitutes Michael Essien and Andriy Shevchenko put a misleading gloss on the scoreline, with Norwich earlier hitting the post through Dickson Etuhu and the bar via Lee Croft.
In the early kick-off, Brad Friedel made a stunning double save from Thierry Henry and Justin Hoyte in the final minutes of the clash at Arsenal to give battling Blackburn a replay at Ewood Park.
The Gunners were also denied a late penalty at the Emirates Stadium after Stephen Warnock's trip on Jeremie Aliadiere 13 minutes from time.
Friedel then threw himself at shots from Henry and Hoyte late on to hand his determined team a second chance as the game finished goalless.
