RICHMOND has consolidated top spot on the ladder, withstanding a fierce challenge from one of its most serious challengers, Sydney, to prevail by 26 points in a gripping contest at Etihad Stadium on Thursday night.

After taking the lead for the first time at the 26-minute mark of the opening quarter, the Tigers were never headed, but the Swans gave them an almighty scare when a Lance Franklin goal cut the margin to four points in the opening minute of the final term.

Richmond had led by 22 points late in the third term, but late goals to Will Hayward and Franklin cut the margin to 10 points at the final break, and then Buddy's last-quarter goal appeared to give Sydney all the momentum.

However, the reigning premiers then asserted their authority, holding the Swans scoreless for the rest of the game while they piled on the final three goals to seal a 14.9 (93) to 11.1 (67) victory.

Jack Riewoldt (three goals) was the hero for the Tigers, turning on a vintage display in attack. His total of 16 marks was six more than the next best player on the ground, while seven of those marks were contested.

The Tigers' win was soured with Reece Conca suffering a horrific injury early in his 100th game.

Conca's left ankle became trapped at an awkward angle underneath Lance Franklin midway through the first quarter, with the Tiger stretched from the ground.

The Tigers now have a game's break over the Swans, who entered the game second on the ladder, and West Coast, although the Eagles can close that gap if they defeat the Crows at Adelaide Oval on Saturday.

The Swans' loss could yet get worse with Franklin likely to face MRO scrutiny for an open-handed shove to the neck of Alex Rance early in the third term, which resulted in a free kick to the Tigers defender.

Richmond defender Nick Vlastuin appears to be in the same boat after he threw an elbow that caught Luke Parker high in the third quarter.

The much-anticipated contest between Franklin and Rance did not quite live up to billing, although it had a couple of flash points.

After Franklin's shove to the throat, Rance appeared to get one back on the Swan later when he smothered a set shot from outside 50m. But the Tiger was pinged for overstepping the mark and Franklin took advantage of the resultant 50m penalty to goal from point-blank range after the three-quarter siren.

Franklin finished with four goals to claim the points over Rance, although he was not at his devastating best.

Toby Nankervis (18 possessions, 41 hit-outs and 10 tackles) decisively won his ruck contest against former teammate Callum Sinclair, while Kane Lambert (27 possessions and three goals), Shane Edwards (23 possessions and one goal) and Trent Cotchin (26 possessions and six clearances) powered the Tigers' midfield on a night when Dustin Martin was well held by Swans tagger George Hewett.

Vlastuin (22 possessions, 10 marks and nine one-percenters) continued his good form in defence, and Jayden Short (two goals and seven inside 50s) gave the Tigers plenty of drive from half-back.

The Swans loss ended a six-game winning streak, while they had won their previous two games against Richmond.

Josh Kennedy (a game-high 37 possessions, eight clearances and nine tackles) led his team from the front as Sydney won the clearance count 39-31.

In addition to keeping Martin on a short leash when the Tiger superstar was stationed in the midfield, Hewett had 20 possessions of his own and a game-high 10 clearances.

Jake Lloyd (33 possessions) and Luke Parker (23 possessions and two goals) were also solid performers through the midfield.
