Former Australian Test wicket keeper Brad Haddin has become the latest player to sign up for the upcoming Pakistan Super League.

The Sydney Sixes, Haddin's current T20 Big Bash League team, confirmed that the 37-year-old will enter the PSL draft with the likes of Kevin Pietersen and Chris Gayle.

The tournament will run from February 4 - 24, overlapping with Australia's tour of New Zealand, meaning there will likely only be a limited number of Australians in the tournament.
