Blackburn came close to causing a huge shock, dominating parts of the first half after an eight-minute delay early in the game following an injury to Liverpool defender Martin Skrtel in an aerial challenge. Skrtel was wearing a neck brace as he was carried off on a stretcher but Liverpool manager Brendan Rodgers said the Slovakia centre back was "fine."
Liverpool pressed in the closing stages, with Jordan Henderson going close, but didn't play the free-flowing football that has helped the team remain unbeaten in the league since mid-December.
Bradford-Reading also went to a replay Saturday. Aston Villa beat West Bromwich Albion 2-0 and is the only team through to the semifinals, which are both played at Wembley Stadium.
The final is also played there on May 30 — the 35th birthday of Liverpool captain Steven Gerrard, who is leaving the club this summer after a 26-year association to move to MLS side Los Angeles Galaxy.
Liverpool can still give Gerrard the perfect send-off but — without its injured captain again on Sunday — the team lacked fluency against committed and well-organized opponents.
"We kept a clean sheet and still have big confidence. We just lacked that final ball," said Rodgers, whose side had won its previous five home games.
