Edinburgh secured a dramatic 15-14 away win over Connacht thanks to Nathan Chamberlain's try and conversion in the final play of the match in Galway.

Connacht academy centre Sean O'Brien marked his first senior start with a fourth-minute try while Magnus Bradbury crossed for Edinburgh on 31 minutes.

Shane Delahunt's converted try made it 14-5 to the hosts at half-time.

Connacht had captain Jarrad Butler sent-off in the 56th minute, with Chamberlain also kicking a penalty.

Flanker Butler's 56th-minute dismissal for a high tackle left Connacht clinging on, but fly-half Chamberlain slalomed through for the killer score which keeps his side in contention for Champions Cup rugby next season.

The Scottish side, whose game last week against Benetton was postponed, came under immediate pressure with Gavin Thornbury, the eventual player-of-the-match, charging down a Charlie Shiel kick.

The hosts kept pressing and worked the ball wide for 22-year-old centre O'Brien to power over in the fourth minute. Jack Carty converted for a 7-0 lead.

Edinburgh lock Bradbury finished off some patient round-the-corner driving but his try owed much to a brilliant initial break past halfway from Chamberlain.

However, with tighthead Jack Aungier carrying forcefully, Connacht hit back on the stroke of half-time. Hooker Delahunt crossed from a second maul attempt near the left corner and Carty added a crisp conversion for a nine-point half-time advantage.

The third quarter developed into a bit of a stalemate, with Edinburgh failing to profit from an advancing maul and the westerners unable to build on a threatening burst from Alex Wootton.

The game swung massively in Edinburgh's favour when Butler was dismissed for his head-high tackle on Andrew Davidson, which referee Chris Busby deemed a 'shoulder charge' with 'no wrap'.

Eroni Sau surged up inside Connacht 22-metre line, and although the home defence held firm, Chamberlain made it a six-point game with a 69th-minute penalty.

Although a Niall Murray line-out steal edged Connacht closer to the finish line, some costly penalties pinned the Irish province back and Chamberlain, after gaining lineout possession, exposed some tiring tackling to touch down and add the vital conversion.
