Samo has played only 30 minutes of rugby spread over the Hurricanes and Rebels matches this season because of his knee injury, but has been playing in Brisbane's Premier Rugby competition for the past month.
The Reds are looking to bounce back from their defeat against the Cheetahs in the last round and McKenzie will be looking to Fijian cult hero Samo to add some attacking punch to his side.
"Radike will bring a new dimension to the way we play and is also a fresh body to further energise the group following what has been a long stretch of matches," said McKenzie.
"We're nearing the end of what has been an extremely demanding period, where we've played 15 games during the past 16 weeks. As such, anytime you get the chance to freshen up and bring new faces into the group at this time of the season is always beneficial.
"We also know the attributes Radike brings to the game, especially with his ball running, and that can only be advantageous against a Stormers team which has conceded the fewest number of tries in the competition to date.
"They've got a good defence and we have to get through it so I'm cognisant of that. We've got to bend the line and get through them and Radike has done that job for us in the past."
Samo played for the Brumbies in their heartbreaking 30-28 defeat to the 2001 Lions. The only other player to face the Lions in 2001 who is still in the mix 12 years later is current Brumbies back row man George Smith
