Tahir is eligible to play when Delhi Daredevils take on Kolkata Knight Riders at the Ferozeshah Kotla Ground, following the IPL Technical Committee's decision to approve the replacement today.
Coulter-Nile had injured his hamstring in the match against Chennai Super Kings on April 21.
Meanwhile, Zaheer Khan of Mumbai Indians and Saurabh Tiwary of Delhi Daredevils too have been ruled out of the IPL for remainder of the season, following their respective injuries.
In accordance with the IPL Player Regulations, the two franchises may each take a replacement player from the list of players who registered for the 2014 IPL Player Auction but were not taken in the auction.
