Mathias will be visiting Lucknow for the tournament which will start on January 17.
At that time, Taapsee will be busy travelling to different cities to promote her upcoming film Baby and because of her hectic schedule she won't attend her beau's tournament.
"Yes he will be in India. But I will be promoting 'Baby' on those same dates," Taapsee said in a statement.
The two met during the inaugural Indian Badminton League last year where Mathias was part of the Lucknow-based team Awadhe Warriors while Taapsee was the brand ambassador of champions Hyderabad Hotshots.
Baby, which also features actors Akshay Kumar and Rana Dagubatti, will release on January 23.
