Smith picked up a groin injury in the match against the Rebels in Johannesburg.
With captain Warren Whiteley and Cyle Brink out with injuries, the Lions will hope the 25-year-old Smith will be fit to play. Whiteley will be out of action for between 4-6 weeks.
Another injury concern for the Johannesburg side will be the injury to another loose forward Vincent Tshituka. The 20-year-old picked up an ankle injury as well as a head injury.
The Lions will really struggle to find the right combination in the loose trio should both players not play this weekend.
Prop Dillon Smith broke his cheekbone and will be out of action for eight weeks.
Fullback Andries Coetzee will also not travel with the side as he is struggling with a hamstring injury.
The Lions fly out to Tokyo on Wednesday evening.
Meanwhile the Stormers feel confident that lock Eben Etzebeth will be available for their match against the Hurricanes in Wellington.
Etzebeth picked up a head injury last week against the Jaguares at Newlands.
According to defence coach Norman Laker the first day of training after the long flight from Cape Town went really well.
“It was a long travel but the guys are okay considering. We had lots of stuff to do today (Tuesday) as obviously we missed the usual Monday session because we were in the air. I thought the guys did well considering the three days of travel,” said Laker.
“Everybody so far is fit to play. Eben passed his first test, so everyone is looking ready and confident,” said Laker.
The Stormers will hope to start their four week tour on a high as they have tough fixtures ahead of them.
