ALUN Wyn Jones is wary of a proud Newport Gwent Dragons side putting a spanner in the works of the Ospreys' push for the playoffs, writes Chris Kirwan.

The Liberty Stadium region need a perfect end to the campaign if they are to overhaul fourth-placed Glasgow to earn a RaboDirect Pro12 semi-final in Ireland.

Most pundits expect them to record a bonus point win in the second game of the Judgement Day double-header on Easter Sunday given that the Dragons have had a shocking 2014.

The Rodney Parade region have won just once in the league since the turn of the year to slip to 10th in the table and were thrashed 45-27 by 11th-placed Treviso last weekend.

But Wales lock Alun Wyn Jones believes Sunday's clash is no foregone conclusion and stressed there is no complacency in the Ospreys' ranks.

He said: "The Dragons have had a couple of tough run outs so we don't want to slip up and give them the scalp they want to get their season back on track.

"We are aware of what a proud side they are and early on in the season they pushed a lot of big sides and got a couple of scalps, so we are not going to take them lightly.

"They have a few dangerous individuals, (scrum-half) Richie Rees has been marshalling them well while they have young guys like (full-back) Hallam Amos really putting their hands up."

For all their courteous talk it would be a blow if the Ospreys, who triumphed 40-17 when the sides met in Swansea in October, fail to bag a five-point haul from Sunday's derby.

Nonetheless, head coach Steve Tandy doesn't want to come a cropper against a Dragons side that have already beaten their playoff rivals Ulster and Glasgow (twice) this season.

"It would be disrespectful to go in thinking about bonus points," he said. "They are a tough outfit and have had some good results, especially at the start of the season.

"We are probably that we are not going to Rodney Parade and it's at the Millennium Stadium. It's all about the win and if we can build a lead then it becomes about scoring tries."
