The 211cm, 105kg attacking big man has been training with the Wildcats and is the latest in a string of signings.
The 26-year-old said it was a dream come true to play for the club he grew up supporting.
‘To play in your home state for the Perth Wildcats, a club with such a rich culture, will be amazing and it’s all a bit of a whirlwind at the moment, but I’m very excited and I’m loving it,’ Jervis said.
‘I always hoped to make it as a pro basketballer, but I felt that dream had almost slipped away, so I got on with my life and got a job, but to get that call from the Wildcats was unbelievable, it’s something I’ve worked very hard to achieve.’
This season Jervis has averaged a double-double with 21.4 points per game at 46.1 per cent shooting, while grabbing 12.4 rebounds, he has also averaged 3.0 blocks, 2.2 assists and 1.0 steals per game.
The Perth Wildcats squad is now taking shape, as Jervis becomes the second last player to sign on the dotted line, after the club signed Miami Heat rookie James Ennis on Saturday.
He also joins his East Perth Eagles head coach Adam Forde on the team, who was recently appointed the technical assistant coach.
The 2013/14 NBL season starts on Friday October 11, where the Wildcats take on Adelaide 36ers at Perth Arena.
