The loss saw Burnside slide to fourth, thanks to a congested table and wins for Lincoln University, Canterbury University, and Marist Albion – who put 70 points on Christchurch.
Just three points separate the top six sides in the Metro rugby competition, with Sydenham and Sumner following close behind.
Sumner will be looking to continue their good recent form – they have won five of their last six matches and hold the DCL Shield – when they take on HSOB away.
Lincoln Uni visit Sydenham, while UC will hope to bounce back from their 43-40 loss to Sumner when they take on Shirley.
The other matches, all between sides outside the top eight, see Belfast host New Brighton and Christchurch take on Linwood.
Metro rugby table: Marist Albion 34; Lincoln Uni 33; UC 33; Burnside 32; Sydenham 32; Sumner 31; HSOB 28; Shirley 21; Linwood 19; New Brighton 16; Belfast 10; Christchurch 6.

Bays beat FC Nelson 3-1 on Sunday in the only other cup match involving a Canterbury side.
The other Southern League matches taking place on Saturday see Christchurch United play Nomads, while Universities host Ferrymead Bays.
On Sunday, FC Twenty 11 will make the trip north to play Nelson Suburbs away.
