Defender Anthony Gerrard says Cardiff's players showed 'grit and determination' in their 0-0 draw against Leicester City.
Cardiff extended their unbeaten run to eight games despite four players suffering injuries during the match.
And Gerrard says the side's resilience is a sign of the team ethic instilled by boss Malky Mackay.
"Every single game we go into we know that every single person is going to give 100 per cent," he said.
"Because if somebody is not, then that's when you get found out."
Cardiff lost Craig Conway, Rob Earnshaw and Mark Hudson through injuries suffered during the first-half.
And despite pulling a hamstring, substitute Rudy Gestede was forced to complete the match with Mackay having used all three replacements.
"We showed fantastic resilience and threw our bodies on the line. The lads showed great grit and determination to hang on and defend really well," added Gerrard.
"We're really proud of the lads the way they performed and the way they dug in."
Despite praising Cardiff's resilience, Gerrard conceded the first-half performance against Leicester had not been up to standard.
"The first half we were really poor to be honest," added Gerrard. "We didn't get going [and] didn't get our passing going.
"But I thought in the second half, the first 25 minutes, we showed what we are made of and put them under a lot of pressure
"But we couldn't get that vital goal and with 20 minutes to go we were down to 10-men virtually [when] Rudy pulled his hamstring."
Manager Mackay is likely to have to make changes for Wednesday night's home game against Championship leaders.
The Scotsman has said he will assess Cardiff's injury list before deciding if he is to enter the loan market.
And Gerrard says Cardiff have capable players within the squad to answer the manager's call if needed.
"We've got no hesitation of changing people if the bodies aren't there," he said.
"We know what we're getting from each and every individual in the squad."
