Kenya Shujaa and Morans launched the campaigns in style while Red Wailers stunned defending champions Samurai as the Safari Sevens got underway at the RFUEA ground on Saturday.
Mwamba speedster Collins Injera announced his return to Safari Sevens for the first time in seven years with two tries that spurred Shujaa to 31-0 victory against Zambia in Pool “C”.
“Shujaa were rusty in the first three minutes and couldn’t get to the rucks. But I am glad they stepped up to control the game with good defence,” said Shujaa coach Paul Feeney.
“It feels great playing at home for the first time since 2012. It's every player’s joy and dream,” said Injera.
