A solidly built player, Chisanga has also been a regular face in the Kenyan national Sevens team on the World Sevens circuit in recent seasons.
Nicknamed “The Beast” by followers of his Kenyan club side, Menengai Cream Homeboys, the back-row player has also gained leadership skills at the Nairobi-based side having captained the team on a number of occasions since first taking over the armband in 2014.
Having completed an initial trial and medicals, Chisanga’s move to the North East sees him become the first full Kenyan international ever to be registered with a Premiership side.
Speaking of the new signing Falcons Director of Rugby Dean Richards said: “Joshua has been brought to our attention and we’ve been very impressed with what we have seen so far.
“He has signed with us until the end of next season and we think there is a lot of talent there ready to be honed and nurtured.
“He has performed well during his trial and we’re looking forward to working with him.”
