Yes it is and its a great match up. This weight is more suited to Khan and this time he will look even better at this weight as his body is becoming used to staying healthy and not dropping down to 140. Note Khan is not pushng for the KO, he is more focused on winning the rounds and outscoring his opponents so he is not putting everything into his shots all the time.
Khan struggles against people who can match him physically for strength and push him back, getting physical etc. It's a good fight although whoever wins should have to fight a Thurman prior to getting Flyd Joy.
I disagree Thurman is fighting on Khan's undercard, lets be real, Khan doesnt have to fight undercard fighters, Thurman is yet to beat anyone in the top 10 in the 147 division, this Khan's 2nd fight at the weight and he already fighting a top 10 fighter.
