Gurbaz, a wicketkeeper-batsman, has played 20 T20 internationals, scoring 534 runs at a strike rate of 138.
The Titans, who are making their IPL debut along with Lucknow Super Giants this season, picked the Afghan player at his base price of $66,000, the franchise said in a press release.

Gurbaz, 20, will be the third Afghanistan cricketer alongside Rashid Khan and Noor Ahmad to feature for the franchise, it added.
The Titans had been looking for a replacement after Roy pulled out of the IPL last month, citing the challenges of staying in the tournament bubble.
The IPL, comprising 70 league matches and four playoffs, will be played over 65 days across four venues in the western state of Maharashtra.
