Origi missed a match for the Norwegian second division outfit while on international duty with the Harambee Stars last week, but with his arrival back in Norway, he was thrown straight back into the reckoning.
His return was not understated, as he performed admirably in the club's 2-1 away win at Tromsdalen on Sunday 21 October 2012.
They had to come from behind to collect the win, with second half goals as well as a string of good saves from Origi giving them the much needed win.
Kjell Vangen opened the scoring on 42 minutes for the home side but KISA hit back through Truls Oranjestad on 45 minutes and Victor Adebahr on 64 minutes for the win.
The win lifts KISA to seventh place in the second division with 41 points from 27 games played 22 points behind leaders Start.
