The Scarlets will have to rely on other results going their way if they are to scrape into the Guinness PRO14 play-offs for another season.
Saturday’s 20-12 loss to Conference B rivals Edinburgh, coupled with Benetton’s last-gasp draw against Leinster in Dublin has left the odds stacked against the 2017 champions.
With just two rounds of the regular season remaining, the Scarlets sit fifth in the table, six points behind Edinburgh in fourth and seven adrift of third-placed Benetton.
The top three qualify for the play-offs with the fourth-placed side going into a match against the fourth-placed side in Conference A to decide who plays in next season’s European Champions Cup.
“Mathematically, we can still do it,” said head coach Wayne Pivac.
“We have two games left and 10 points up for grabs. We need to take those 10 points and do what we can do and hope for a little help from the big man and for other results go our way.”
Reflecting on the Edinburgh game, which saw the home side race into a 12-0 lead, Pivac added: “We were really happy with the first half and the way the boys were controlling the game, but we lost our way after half-time.
"We didn't get too many decisions going our way during the second half, which was disappointing. There were quite a few things coming through the earpiece (from the assistant referees) and ignored.
“But that is gone, you can’t do anything about that now and all we can focus on is next week.”
Scarlets host Zebre at Parc y Scarlets next Saturday (5.15pm kick-off) before taking on the Dragons at the Principality Stadium in the opening match of Judgement Day VII.
