London have been relegated from Super League after losing their final game of the season 19-10 away to relegation rivals Wakefield.
Trinity finished on 22 points, level with Huddersfield, as both sides finished two points clear of the Broncos after the Giants won 24-22 at home to Catalans.
Hull FC's 22-6 home defeat to St Helens meant they failed to overhaul Castleford for the final play-off spot. Hull KR would have needed to win had London won, but, as it was, their loss at Salford mattered little.
