In his absence, Hogg has claimed five wickets in two IPL T20 cricket matches.
Architect of KKR's title triumphs in 2012 and 2014, Narine underwent fresh test on his bowling action in Chennai on Thursday after the BCCI banned him from bowling the off-breaks.
KKR opener Uthappa said it is a difficult phase for the bowler but insisted that Narine is an extremely hardworking and resilient character.
"We're a very tight-knit unit and it definitely leaves us confused. He's someone who adds so much of value to the side. We respect his skills and his contribution to the team immensely. We definitely miss him but we're confident that he'll come through this stronger," Uthappa told a post-match news conference at Eden Gardens.
Narine is expected to join the side when it travels to Bangalore today.
Amid the turmoil, Aussie veteran Hogg, who was drafted in place of Narine, lifted KKR's morale with stunning performances of 1/18 and 4/29.
Uthappa said both the bowlers are very different and could be deadly if they bowl in tandem.
"They are like chalk and cheese. Hogg is a very different bowler. There's a massive difference between them but they are equally effective. It's a good replacement. It's good to have him at hand when we miss someone like Sunil. But if they're both together it would have been an extremely lethal bowling attack," he said.
Showering praise on the Aussie, Uthappa said the 44-year-old brought in an air of positivity to the side.
"Hogg brings in a lot of good energy into the side. He's an extremely funny character. It's unimaginable for a 44-year-old to have that kind of energy. Some of us find it difficult to keep up with him.
"He's lot of fun on the field and keeps fooling around, He's definitely the prankster in the unit. When it comes to the skill, he's very effective and brings in his experience and positivity. He exactly knows what he's doing," he said.
