IT is time to get your calculators at the ready as Nottingham's British and Irish Cup hopes come down to Sunday 24th February's clash with Llandovery at Meadow Lane Stadium (2.15pm kick-off).

David Jackson's 100^th career try (celebration pictured) was enough to ensure Nottingham scored a crucial away win over Doncaster and that everything is still to play for in the last group game of the cross-border competition.

AS IT STANDS

What the Green and Whites need to do now is score a bonus-point win over the Welsh Principality outfit and ideally keep the visitors' attack quiet.

But it is never that easy.

This is the easy to follow guide of what Nottingham needs to do to progress to the next stage:

WIN and...

• Score four or more tries in the process.
• Concede less than four tries.
• Win by 10 or more points in the process.
