FA Cup fourth round

There are 12 FA Cup fourth round fixtures on Saturday, with Leicester City travelling to play Peterborough in the day’s early kick off (BT 2, 12.30pm). Southampton take on Watford in one of two all-Premier League ties (3.0pm), before Tottenham Hotspur travel to play League Two Newport County in the evening fixture (BT 2, 5.30pm). Later, West Bromwich Albion face Liverpool at Anfield (BT 3, 7.45pm).

Racing from Cheltenham and Doncaster (ITV 4, 1.30pm-4.0pm; TV3 1.0pm-4.0pm)

The spectre of the Cheltenham Festival looms ever larger over the National Hunt season and there is a fine offering at Prestbury Park on Saturday, with four Grade Twos on the card. The highlight is the Cotswold Chase (2.25) - a key trial for the Gold Cup - with Bristol De Mai currently a 5-4 antepost favourite. Meanwhile Finian’s Oscar heads the field in the Cleeve Hurdle (3.35) after being reverted to hurdles following a brief spell chasing. Colin Tizzard’s star in the making is an 11-4 favourite but an emotional victory for Beer Goggles - whose trainer Woollacott died earlier in the week - would bring the house down.

There is also a strong card at Doncaster, with Davy Russell to take the ride on L’Ami Serge in the Sky Bet Handicap Chase (3.15). Saturday’s Irish racing comes from Fairyhouse.

The National Football and Hurling leagues return

There are seven inter-county fixtures on Saturday as the National Leagues begin in anger.
