"I'm pretty sad I'm leaving, but I think I've had a great stint here," said Kebble who recently made his 100th Warriors appearance. "All good things have come to an end. It's not really a reality yet, we've got three big weeks to go, so I haven't thought about it much.
"The awards dinner on Saturday was the first time I've thought about it properly. It's quite sad, but if you stay too long you become a villain, so I'm glad I'm leaving a hero!"
Joining in 2017, the former South Africa U20s prop went on to play for Scotland and was part of the Glasgow sides that lost in the finals of PRO14i n 2019 and the Challenge Cup last season.
Kebble will now face his former side, the Stormers, on Saturday for a place in the URC semi-finals, before making a big decision on his future - although he's keeping his cards close to his chest'
"I've got a decision to make this week, it sounds like. That's all I can say right now."
Looking back at this time in Glasgow, Kebble said: "Making the [2019] final at Celtic Park was really special.
"Being a really competitive side every year, we've done well every year even if we haven't won anything. To top it off this season with a trophy would be lovely and a good way to end it.
"The guys who did experience that [final] will have a little extra knowledge when it comes to finals rugby. For us, we're completely a different team. We just need to focus on being the best we can be for ourselves and when it comes to those big moments hopefully we can be a little bit luckier."
