Carver said: "There certainly wasn't anyone on the beach with their flip-flops on, that's for sure.
"After the comments last week, which were ridiculous, from ex-players - I'm surprised at that - every single one of them, and I include the lads who came on the pitch as second-half substitutes, gave everything for this football club.
"It showed that they are not on their holidays yet."
That barb was aimed in the direction of Match of the Day pundit Phil Neville after his comments last Sunday night, although the former Manchester United and Everton man tweeted during the second half: "Newcastle been brilliant 2nd half so far!".
When informed, Carver said: "That's nice, I didn't realise that had happened."
Defeat, coupled with Crystal Palace's 2-1 victory at Stoke, saw Alan Pardew's Eagles leapfrog the Magpies into 11th place, although the former Magpies manager's progress was of little concern to Carver.
He said: "I've got to be honest, it is because of the situation we are in. Congratulations to Alan, but I am not worried about Crystal Palace.
"The only thing that's on my mind and the only thing I'm worried about is this football club and making sure everything I do is 100 per cent, everything the players do and give is 100 per cent, and that's all I can ask for."
