FA Cup Previews: Swansea eye another upset

In the first of only two all Premier League ties, West Ham United will give late fitness tests to Valon Behrami and James Tomkins before their home game with Middlesbrough after the pair missed midweek internationals.

Fulham face a dangerous trip to Championship promotion chasing Swansea City without midfielder Dickson Etuhu who hobbled off the pitch in last week's 0-0 draw with Wigan Athletic.
Defender Aaron Hughes is also struggling after sustaining a dead leg on midweek international duty while on-loan Inter Milan midfielder Olivier Dacourt may make his debut against the side who are one place outside the playoff place and unbeaten in 15.
Blackburn Rovers manager Sam Allardyce will give opportunites to a number of fringe players for the visit of championship side Coventry with his side fighting for Premier League survival.
"There will be opportunities for some of the more fringe players, but that is not because we are taking the FA Cup lightly - quite the opposite. I believe a good cup run only help our league form," he told the club's website.

Aston Villa manager Martin O'Neil was frustrated that striker Emile Heskey aggravated the same Achilles injury that forced him to limp off against Blackburn last week while on international duty for England.
"It's a problem for us because he is touch and go for the game on Sunday," O'Neill told the club website. "The friendlies from a club perspective are an absolute waste of time."
