Leinster's defence of their Celtic League title is in tatters after they lost their fourth match on end - 18-23 to Scottish new boys Borders.
Leinster now have to win their final two matches, secure two bonus points and hope other results go their way if they are to make the quarter-finals.
Edinburgh thumped a poor Llanelli outfit 38-14, while Ulster ended Munster's unbeaten run with a 26-17 victory at Ravenhill.
Scrum-half Neil Doak, an Ireland cricket international, scored all of Ulster's points to add some spice to the Pool A table.
Neath all but confirmed a quarter-final berth with a comfortable 34-7 win over Ebbw Vale, thanks to a hat-trick of tries to fullback Gareth Morris.
Vale flanker Tyrone Morris must have broken a record when he was sin-binned 30 seconds after coming on as a replacement, in his first appearance since being red-carded against Caerphilly a fortnight ago.

The programme has been funded by the Hunter Foundation.
The WRU has launched a campaign to create a long term legacy for Welsh club rugby by highlighting the advantages of volunteering. Rhian Edwards, a volunteer at Seven Sisters, has enjoyed many benefits of her volunteering at a grassroots rugby club including being part of the Rugby World Cup volunteer workforce after being nominated by the WRU - and the WRU is asking for more people to develop their 'Welsh rugby roots'.
