Bahrain are the favourites in this tie, but neither nation has enjoyed a particularly spectacular campaign, and this game is in danger of being a bit of a dead rubber.
Bahrain are currently third in Group C, three points off second-placed Bahrain and five points off group leaders Iraq.
Despite the slim margins, the general narrative of the group suggests that Bahrain have not done enough this term to warrant qualification from the group.
The last time these two sides met was in November 2019, and it ended 0-0, with no side really seizing the opportunity.
Hong Kong have given this campaign a good go, but the minnows are still a long way off the pace in terms of keeping up with the big boys of the group.
Currently fourth in the group, Hong Kong have five points, four better than last-placed Cambodia, who have conceded 44 goals in eight games.
Hong Kong have picked up one win so far, against Cambodia, and two draws, against Bahrain and Cambodia.
Head coach Mixu Paatelainen will hope his side can go that step further this time out and beat Bahrain.
Bahrain could look to shake things up on Tuesday after the side lost to Iran last time out.
Fung Hing Wa scored an own goal for Hong Kong earlier this week and could face a spell on the bench as a result.
Bahrain possible starting lineup:
Jaffer; Madan, Al-Shamsan, Al Hayam, Nabeel; Mahoon, Al Malood, Isa; Al-Romaihi, Al-Shaikh, Al-Humaidan
Hong Kong possible starting lineup:
Fai; Kit, Wa, Helio; Wai, Orr, Eli, Roberto, Yang; Ha, Chan
We say: Bahrain 1-1 Hong Kong
We are not expecting too many fireworks from this one, but both sides do have the players to hurt one another. We reckon this one could end in a stalemate.
