A leg-spinner by choice, Dubey originally hails from Azamgarh in Uttar Pradesh but plies his trade for Karnataka in the domestic circuit. It was the University Cricket Championship in 2012 that brought Dubey's talent to the table and he struck a few eye-catching knocks for his team - VBS University - including a swashbuckling 61-ball hundred. Having decided to take up cricket as a career, he came to Bangalore in search of better prospects. Dubey made his List-A debut for Karnataka in 2015 but wasn't given a long rope. He made his way back into the state team in 2018 for the Syed Mushtaq Ali trophy, however, he failed to cement his spot in the team. It was in 2019 that he got a fresh lease of life through some strong shows in the Karnataka Premier League and it paved the way for his entry into Karnataka’s team for the Vijay Hazare Trophy. He played 5 matches and claimed 9 wickets without getting many opportunities to bat. Shreyas Gopal's poor form saw Dubey replacing him for the semi-final and the final. In the summit clash, Dubey had a forgettable outing but he turned out to be the lucky charm as Karnataka were crowned the champions for the fourth time. A rookie, Praveen Dubey made headlines when he was snapped up by the Royal Challengers Bangalore for INR 35 lakh in 2016. Without even playing a single first-class game, Dubey had secured an IPL contract at the age of 23. The all-rounder was a renowned name in the Karnataka Premier League and it was in the 2015 edition of the tournament that Dubey stole the show after taking 10 wickets in 8 matches with an economy of under 7; it also prompted the Bangalore franchise to bid for him and thus he became the only player from Karnataka to feature in the squad that season. RCB ended up buying him back for a lower price of INR 10 lakh in 2017 but he couldn't impress Virat Kohli and company and that meant that he was benched throughout the season. It wouldn’t be until 2020 that Dubey would finally get to make his IPL debut after replacing an injured Amit Mishra at the Delhi Capitals.
