Sarries are definitely having the better of the set-piece, twice turning over at the line-out through lively lock Maro Itoje and now, for a second time in the match, their pack gets a shove on at the scrum to win a penalty.

The home fans are up in celebration as Ernst Joubert touches down, but Mike Ellery had placed a foot just into touch earlier in the move so it won't count.

An otherwise relatively quiet opening nine minutes or so in north London.

The visiting Exiles have started brightly at Allianz Park, kicking an early penalty to touch and getting a rolling maul moving towards the try-line.

But eventually the ball is knocked on and Saracens will insert at scrum time.

A Harlequins side including England skipper Chris Robshaw, of course. Full team news to follow shortly.

Saracens fly-half Owen Farrell boots the ball long to get this afternoon's Premiership action under way.

Sarries are in their traditional red and black, London Irish in white.

Played two, won two meets played two, lost two at Allianz park this lunchtime.

There's no let up for Tom Coventry's Exiles as they face the defending champions following defeats against Leicester and Exeter.

But Irish can cling to the fact they are one of only three sides to beat Sarries here - a 22-13 victory back in February 2014.
