The Hammers are today aiming to reach the FA Cup fifth round for the first time in five years.
Defeats to the likes of West Brom, AFC Wimbledon and Wigan in recent years have frustrated the locals, but there is confidence of a building Cup run in east London.
Doncaster, though, have been known for a cupset or two down the years and should not be taken lightly, but will be making a rare foray deeper into the competition with victory at the London Stadium.
David Moyes is expected to show the League One side respect with a strong line-up, though youngster Ademipo Odubeko could be afforded a chance to impress.
The winner this afternoon will set up a date with either Manchester United or Liverpool, who face off at Old Trafford tomorrow, for a place in the quarter-finals.

Captain Mark Noble is expected to start while Fabian Balbuena and Issa Diop should get a chance at the back.
Michail Antonio is back fit but the Hammers must manage him carefully as the only senior striker, though Moyes has suggested more minutes might be exactly what he needs.
