Warner was playing for New South Wales against Phillip Hughes's South Australia when Hughes was struck

Australia batsman David Warner says he does not know how he will react when he returns to the ground at which Phillip Hughes was fatally struck.

Australia face India at the Sydney Cricket Ground in the fourth Test of their series, starting on Tuesday.

Warner was fielding for New South Wales when close friend Hughes was hit by a Sean Abbott bouncer on 25 November. Hughes died two days later.

"It's going to be tough. I've got to hold back the emotions," Warner said.

The 28-year-old dedicated his century on the opening day of the first Test of the series to Hughes, gesturing skywards when he reached three figures.

Australia won that match and have already secured the series by taking a 2-0 lead with only one Test remaining.

The hosts will be without pace bowler Mitchell Johnson, who has a hamstring injury, and Warner knows he and his team-mates face an "emotional" time.

Australia batsman Hughes, 25, was batting at the Randwick End of the ground when he was struck.

Warner said: "I know when I go to face up at that end, I'm going to be looking down at that spot. I honestly can't tell you how I'll feel until I get out there."

Australia team-mates Brad Haddin, Nathan Lyon and Shane Watson were also playing in the match during which Hughes was struck.
