The Irish sportstars in action on Sunday

9.30am Rowing

Depending on today’s results in the heats, Sanita Puspure could be back in the water as early as Sunday morning in the repechage.

That’s the worst case scenario, with Puspure aiming for a place in Tuesday’s quarter-finals instead.

10.45am Swimming

Sycerika McMahon, silver medallist at the European Championships over 50m, will be making her Olympic debut in the 100m breaststroke.

With the slowest qualifying time in Heat 4, it will be a major achievement for the Portaferry teenager to advance to Sunday evening’s semi-finals (starting at 7.30pm).

11.50am Equestrian

The final two members of the eventing team, Camilla Speirs and Mark Kyle, will be judged on the second day of the dressage competition. Speirs will be put through her paces at 11.52am, with Kyle due on at 3.10pm.

1.35pm Sailing

Peter O’Leary and David Burrows need no introduction to the Weymouth having won gold in a pre-Olympic regatta last month. The Cork-based duo take to the water for the first of at least 10 races in the Star class at 1.35pm, with the second taking place at 2.50pm.

2.50pm Canoeing

Eoin Rheinisch, who missed out on a medal by the narrowest of margins in Beijing, goes in the heats of the K1 Slalom on Sunday lunchtime.

The 32-year-old has not had the ideal preparation with injuries taking their toll but should certainly hope to advance to Wednesday’s semi-finals.

7.10pm Badminton

World number 44 Chloe Magee opens her Olympic campaign in the round robin format against Pi Hongyan of France, a former world number two. Regardless of this result, Magee will get another bite at the apple when she meets Egypt’s Hadia Hosny on Tuesday.

10.15pm Boxing

Adam Nolan (below) is on the night shift at the Excel Arena, the Bray Garda not due in the ring until after 10pm when he will meet Ecuador’s Carlos Sanchez Estacio.
