Nottingham Forest host the reigning FA Cup holders and bitter rivals Leicester City in the fourth round on Sunday afternoon.
The Championship outfit have already knocked a Premier League side out of this season's competition, dumping Arsenal out in the previous round. Leicester themselves faced top flight opposition in the third round, but eased to a 4-1 win over Watford in January.
Here's all you need to know about the upcoming tie.

Nottingham Forest team news
Top scorer Lewis Grabban cut a worrying figure as he had to be helped off the pitch during Forest's deflating 2-1 defeat away to Cardiff City last weekend. January arrival Steve Cook was also forced off with a calf strain that may not be as serious as the ankle injury which left Grabban in a boot post-match.
The 34-year-old striker is set to join Joe Worrall (fractured rib) and wingers Alex Mighten and Joe Lolley (both knee) on the sidelines this Sunday.
Leicester team news
Leicester's injury concerns have hardly subsided over the international break. Defenders Jonny Evans, Timothy Castagne and Ryan Bertrand have been ruled out for the foreseeable future after the trio underwent operations in January.
Jamie Vardy managed to avoid going under the knife but isn't expected to return until next month as he nurses a hamstring injury.
In positive news, Kelechi Iheanacho and Wilfred Ndidi have returned to the fold following Nigeria's exit from the Africa Cup of Nations - though the continued involvement of Nampalys Mendy's Senegal rules him out.
Ricardo Pereira's latest return remains doubtful though Wesley Fofana could make his first appearance of the season some time in February.

Nottingham Forest vs Leicester head-to-head record
In a 2003 Football Fans Census, Leicester supporters named Nottingham Forest as their main rivals. Forest, incidentally, opted for another east Midlands team - Derby Country - as their chief enemies but this remains a match with more meaning than a random encounter.
Leicester boast a narrow advantage in the 104 meetings between the sides, recording 40 wins to Forest's 38 across all competitions (26 draws apiece).
The sides haven't met since they shared the Championship in 2014. The last FA Cup meeting between the pair ended 4-0 to the Foxes in 2012, as Jermaine Beckford became the second ever Leicester player - after Don Revie - to score a hat-trick against Forest.
Nottingham Forest vs Leicester score prediction
Forest's deserved 1-0 victory over Arsenal in the previous round sparked a four-game winning streak which last weekend's dour defeat in the Welsh capital punctured.
Stripped of their leading scorer, Forest may not be able to exploit the porous tendencies of Leicester's backline - a weakness the Foxes' in-form forwards have often compensated for nonetheless.
Prediction: Nottingham Forest 1-2 Leicester
