The Aviva Premiership action continues with a double-header on Sunday February 23rd, following tomorrow's RBS Six Nations clash between England and Ireland.
Saracens and Leicester Tigers are both in action, with their respective fixtures against London Irish and Exeter Chiefs set to air live on BT Sport 1.
London Irish v Leicester Tigers is up first at 1pm, as last year's champions travel to the capital to take on a resurgent Exiles side.
Irish are on a three-game winning streak in the league, having battled to a narrow 23-20 victory away at London Wasps last week.
Leicester edged out Gloucester in a tight 11-8 win at Welford Road, with a late Toby Flood penalty sealing the points for the home side.
The Tigers are now level with fourth-place Harlequins on 40 points as they target yet another appearance in the end-of-season play-offs.
London Irish remain in ninth on 25 points, five points behind Exeter Chiefs.
Second-place Saracens will hope a win at home to Exeter (kick-off 3:15pm) will be enough to regain the top spot in the Aviva Premiership table.
Sarries are a point behind Northampton Saints at the summit, after both sides recorded wins last week.
Northampton cruised to a 30-14 win over bottom-place Worcester Warriors, while Saracens won away at Sale Sharks 15-10.
Exeter's recent slump continued, with the Exiles beaten for the fourth successive league game. They went down 27-23 at home to Bath, with a losing bonus point the only consolation.
After contending at the right end of the table for the first half of the season, Rob Baxter's side have fallen to eighth place.
