I heard that too C58. The BBC website also has the fixture down for the Tues night, so I'd imagine ITV jumped the gun and made a boo-boo.
Guess it is more TV money as there are only 2 replays so us on Tuesday and Forest/Preston on Wednesday. Presume it is on the box, anyway.
It is indeed on TV and therefore a change in kick off time. "The Club can confirm that our FA Cup with Budweiser Fourth Round Replay against Sheffield United on Tuesday 4th February will be televised live on ITV4. Supporters are advised that the Craven Cottage fixture will now kick-off at 7.45pm, rather than 8pm as was previously advertised. Tickets for the match are now available for Season Ticket Holders and Members to purchase, priced at £15 for adults, £10 for 16-20 year olds and over-65s, and £5 for under-16s."
Wish I lived closer so I didn't have to depend on the tv coverage, but delighted at another chance to catch Fulham on telly. Thanks for the tip off, Cottager.
