Early career
Taleb began his professional career with a unanimous decision victory, before losing his next bout via TKO. After a further four victories across Canada, Taleb fought Pete Sell at Ring of Combat 38 for Sell"s welterweight championship. Taleb was the much quicker man and was able to move in and out of range quickly, which reduced the amount of strikes he took from Sell. In the second round, Taleb hit Sell with a counter right hand, followed by strikes on the ground.
Bellator
In 2011, Taleb was signed by Bellator and made his debut at Bellator 64 against Matt Secor.
Taleb dominated the fight and outclassed Secor enough to be awarded 10-8 rounds by one judge. Taleb was able to take Secor down multiple times and also controlled the stand-up portion of the fight.
Taleb"s second fight for Bellator was against Matt MacGrath, which was held as a 180lb. Catchweight bout, due to the fight being contested at short notice.
Taleb controlled MacGrath in the opening round, by utilising his reach advantage via straight punches.
