And the Glasgow skipper says he is "buzzing" to fitness after being out injured since October.
Steyn will start on the wing at Hampden on Sunday for Warriors' first ever match at the national football stadium and is raring to go after a frustrating spell on the sidelines.
"I'm just really excited to be back out there with these guys," Steyn told BBC Scotland.
"That's always the toughest part about being injured, you miss being able to contribute, you miss the feeling of being out there. That first European window, the atmosphere, you kind of missed out on that, so I'm just buzzing to be back out there with the boys.
"This is kind of the crunch time of year, these six games, the two European windows and then the derbies. To the boys that have been playing, great job so far.
"We've used so many of our squad and everybody that's put the jersey on has stepped up. I think we're just looking to try and add some momentum to that and keep it going.
"Being in Hampden and how many tickets we've sold, obviously I missed these games last year, so really excited to be back for this one."
