The two 2013-14 Aviva Premiership semi-finals form the centrepiece of a bumper weekend of rugby union action on BT Sport.
Viewers will be able to watch the crunch clashes between Northampton Saints and Leicester Tigers, and Saracens and Harlequins, in addition to several other key games.
The first play-off, which kicks off at 7:45pm on Friday May 16th, sees last year's champions Leicester travel down the M1 to Franklin's Gardens.
Northampton claimed home advantage by finished second in the Aviva Premiership league season, four points ahead of their third-place rivals.
Leicester go into the game full of confidence having beaten Saracens 31-27 last time out, but the Saints also enjoyed a big win last weekend, thumping London Wasps 74-13.
The Tigers have been the form side in recent weeks, and courtesy of their unrivalled record in the play-offs, have the psychological edge.
But having lost to Leicester in the Aviva Premiership final at Twickenham last season, Northampton will be fired up and determined to gain revenge.
BT Sport viewers can watch the second play-off game - Saracens v Harlequins - at 2pm on Saturday May 17th, live from Allianz Park.
The London derby pits Sarries, who finished top of the league table, against fourth-place Quins, who grabbed the final qualification spot on the last day of the season.
A hard-fought 19-16 win against Bath - who needed to avoid defeat to secure a play-off spot - ensured Quins extended their season for at least another week.
Saracens go into the game as favourites, having finished 20 points ahead of Quins and holding home advantage.
However, a 27-13 home defeat to Northampton at the same stage last year put pay to Saracens chances - a fact that will not be lost on Mark McCall's men.
BT Sport viewers have three other union encounters to look forward to this weekend, including the first leg of London Wasps' European play-off against Stade Francais.
Wasps will fight it out with the French side for the 20th and final spot in the rebooted European Rugby Champions Cup for next season.
The home leg will be broadcast on BT Sport at 3pm on Sunday May 18th, with the decisive trip to Paris coming a week later at 1:45pm on Saturday May 24th.
There are two more big games for rugby fans on BT Sport this weekend - the two semi-finals from France's Top 14 competition.
Toulon v Racing Metro kicks off at 7:45pm on Friday May 16th, live on BT Sport 2, while Montpellier v Castres is live on the same channel at 3pm on Saturday May 17th.
