That was quite a day, filled with plenty of close contests, more than many expected. But which did you enjoy most? Share your opinion with the vote below.
22:18
RESULTS: Fivers 27:35 Berlin; Pelister 24:32 Magdeburg; Sporting 25:29 Plock
Michal Daszek was everywhere in the second half as his seven goals led Plock to a hard-fought and incredibly valuable away win in Lisbon. In a match where they showed at times that they had what it takes to win, Sporting will be left to rue a poor goalkeeping return of just four saves, compared to 14 by Plock's Adam Morawski.
Magdeburg were in control from the very start in their win, with Omar Ingi Magnusson's 10 goals the highlight. It took a lot longer for Berlin to get going but in the end they proved to be too much for their hosts in Vienna.
22:07
Magdeburg are just minutes away from a big win and one foot in the quarter-finals, leading 31:23. It has been a much improved second half from Eurofarm Pelister but the damage was already done.
21:59
A pair of penalties for Niko Mindegia have give Plock a three-goal lead for the first time tonight, 22:19. Sporting have been up to the task so far tonight but will need to dig deep in the final 12 minutes to turn this around.
21:50
Füchse Berlin have come out all guns blazing in the second half and it hasn't taken them long to grab the match by the scruff of the neck. We've just passed the 40-minute mark and they now lead 26:17, a 9:2 run in the second half.
21:42
Jannick Green is having an evening to remember here. He has saved eight of the 14 shots he's faced so far, an incredible 57% and this is one of his best.
His teammates are not too bad either and Magdeburg lead 21:12 after 38 minutes.
21:26
HALF-TIME: Fivers 15:17 Berlin; Pelister 9:15 Magdeburg; Sporting 15:15 Plock
Two of the group winners aren't having it all their own way so far tonight. In a game that still feels like it has yet to hit top gear, Sporting and Plock go into the break all-sqaure. Neither will be delighted with how things are going but will be confident of getting a result tonight.
Füchse Berlin enjoyed a late flourish to take a two-goal lead but aren't enjoying much else about this challenge. Fivers will be giving Lasse Andersson nightmare's tonight as he was blocked down over and over again before being taken off.
21:16
With eight saves from Wolfgang Filzwieser combined with some smart and brave play all around, Fivers are still in touch with Füchse Berlin. Six minutes left in the first half and they trail by a single goal, 15:14!
21:04
We have two very different games in Lisbon and Vienna.
While Plock have recovered from a slow start to draw level with Sporting, 5:5, we've had more than twice as many goals between Fivers and Berlin, with the young Austrian's keeping pace with their esteemed rivals, trailing 11:10 after 16 minutes of play.
20:58
After going 4:0 down at the start of their game against Magdeburg, Pelister have found their stride somewhat, but it still feels like it could be a long evening for them if they don't find a way past Jannick Green on a regular basis. It's 6:3 to the German side after 12 minutes.
20:50
Fivers' hopes of causing an upset today were dealt a blow over the weekend as top scorer Lukas Hutecek was ruled out for the next few weeks with a finger injury.
After a high-paced opening five minutes, they trail Berlin 6:4.
20:36
Four down and just three games remaining tonight, all beginning in just a few minutes' time.
We have three group winners taking on fourth-placed sides in this block, so it will be fascinating to see which of the underdogs can push their opponents harder and perhaps snatch a win.
Sporting CP (POR) vs Orlen Wisla Plock (POL)
Fivers (AUT) vs Füchse Berlin (GER)
HC Eurofarm Pelister (MKD) vs SC Magdeburg (GER)
Before they begin, check out Hugo Descat's match-saving penalty from a few minutes ago!
20:22
RESULTS: GOG 33:31 CSKA; Nexe 25:27 Rhein-Neckar Löwen
GOG manage to just about keep CSKA at bay to claim a two-goal win.
Who knows how important that late fast break goal by Emil Jakobsen will prove to be as the young Danes will have a slender advantage to defend next week in Russia, where home advantage may be more of a factor with a crowd present.
Seven goals from Halil Jaganjac wasn't quite enough for Nexe as they ran out of gas a bit late on in their game against Löwen, falling to a two-goal defeat. Anything is possible in the return fixture but the German club will be confident of getting the job completed at home next week.
20:14
RESULT: Montpellier HB 27:27 Kadetten Schaffhausen
An audacious in-flight by Sebastian Frimmel gives Kadetten a lead with less than three minutes remaining. It doesn't last long but that doesn't stop them from coming back and scoring another. Finally, it's a Hugo Descat penalty with the last throw of the game that saves a draw for the home side
This fearless approach was key for them today, alongside 15 saves from Kristian Pilipovic, in securing a brilliant draw that it's fair to say is a surprise to most of us.
One of the favourites for the title have a job to do in Switzerland next week to keep their aspirations alive.
20:03
Oooh, it's getting tight in all three matches heading into the final 10 minutes. GOG lead by one, Schaffhausen now lead by one and Rhein-Neckar Löwen have also taken a one-goal lead. You couldn't write a better script!
19:52
A quickfire trio of goals from one-time Kiel player Dener Jaanimaa brought CSKA back within two-goals of their guests before future Flensburg man Emil Jakobsen restores GOG's three-goal lead at 24:21 with 10 minutes played in the second half.
Neither side wasting any time in their attacks, which makes this three-goal gap quite perilous...
19:46
Can Nexe keep their fight going for another 30 minutes? It would be one hell of a result if they can. The second half in Croatia is underway!
