1. #OLD FIRM This madness is why we love Celtic v Rangers clashes – but probably why they don’t usually play the derby at night.

The Scottish Cup fifth round replay saw Rangers ultimately have three players sent off, manager Neil Lennon and Gers boss-in-waiting Ally McCoist clashed on the sideline and the Bhoys squeeked through thanks to a Mark Wilson goal.

Lennon’s side will now face Inverness Caledonian Thistle in the quarter-finals as Celtic remain in contention to complete a domestic treble, a feat now out of Rangers’ reach.

We’ll have more later.

The Irish humiliated England in Bangalore in a victory that is hard to put into context. Read how it happened in our minute-by-minute, the Twitter reaction, who the real winners are and check out the best images from a memorable day.

3. #SIX NATIONS The Ireland squad – currently in camp at Carton House in Kildare – will train this morning. Afterwards members of the squad and management will face the press. Expect the first question to centre on cricket.

Elsewhere, Manchester City tonked a sorry Aston Villa 3-0.
