The Hammers comfortably beat their Championship opponents 3-0 at the London Stadium in their Carabao Cup third round tie.
Angelo Ogbonna, Diafra Sakho and Arthur Masuaku got on the scoresheet as Slaven Bilic rotated his side.
With 20 minutes to play, ex-Manchester United and Real Madrid striker Chicharito was introduced.
While he searched for his first goal at home for West Ham, Hernandez found himself kicked to pieces as the game drew to a close.
Hammers fans were left with hearts in mouths too when their star goalscorer went down clutching his ankle.
But fortunately for West Ham ahead of their crunch London derby this weekend at home to Tottenham, Hernandez shook off the many blows.
And Noble claims he and Hernandez are both ready for Saturday’s showdown (12.30pm) on the back of cup progress.
On Hernandez, Noble told Starsport: “Yeah, he came on and got kicked about eight times.
“I’m pretty sure their lads wanted to say ‘I’ve booted Chicharito’.
“These nights are always tough obviously playing a Championship side, obviously they’re struggling a little bit in the league but you know what you’re going to get.
“But to be honest it was nice for him (Hernandez) to get out there again at home and as we’re fine with no injuries we’re looking forward to Saturday.”
Noble returned to action himself last night after a short absence due to a knee injury.
The West Ham skipper missed last week’s 2-0 win over Huddersfield and Saturday’s goalless draw at West Brom.
However, following a 77-minute run out against Bolton, he insists he is 100 per cent ready and will be in contention to face arch-rivals Tottenham.
Bilic, though, must decide whether to recall Noble or stick with Cheikhou Kouyate and Pedro Obiang in the middle.
Asked about his fitness, Noble added: “Yeah yeah, I feel much better. Obviously it was just nice to get back out on the pitch get some minutes under my belt.
“I ain’t been out for long, it’s only been 10 days, you don’t lose your fitness that quick.
“But it’s the first time, apart from the (groin) operation I had that I’ve had some time off. It’s strange for me not being involved, that ain’t right for me, but it was lovely to be back out there tonight and back amongst the players.”
While Noble is back, Edimilson Fernandes is also returning to training, leaving just James Collins (ankle) and Manuel Lanzini (knee) on the sidelines.
Collins is out for two to three weeks, while Starsport understands Lanzini could be back for the game after Spurs at home to Swansea next Saturday.
Noble added: “Yeah of course, just Manu who’s out of the picture, hopefully we’ll be getting him back soon as well. But at the end of the day, in the Premier League now, winning’s all that matters.
“At the moment, we’ve kept three clean sheets in a row, won two out of the last three. Things are looking better but we’ve got a massive game here Saturday.”
