South Africa's 'Blade Runner' Oscar Pistorius has decided not to defend his T44 200m title in the Olympic Stadium, but there's still some top Athletics activity on Day Three with two men's 100m finals featuring Australian Evan O'Hanlon (T38) and Ireland's Jason Smyth (T13). The 25-year-old from Derry broke both world records in the 100m and 200m in Beijing and it'll be thrilling to see if the Irishman can do the double again. In the Aquatics Centre, Beijing 2008 Paralympic Swimming starlet Ellie Simmonds makes her first appearance of the 2012 Games in the S6 400m freestyle at 5.56pm. Aged just 13, Simmonds won gold medals in both the 100m and 400m freestyle in Beijing to become Britain's youngest ever Paralympic medallist. Watch out for Brazilian swimmer Daniel Dias who is also in action. At 4pm at the Royal Artillery Barracks Matt Skelhon defends the R3 10m air rifle prone (mixed) SH1 Shooting title he won in Beijing – but will face competition from Sweden's Jonas Jacobsson, the most successful Paralympian ever. In Judo, Britain's Paralympic equivalent of the Brownlee brothers compete as Sam Ingrams features in the -90kg category and older brother Joe takes a bow in the +100kg event, which is expected to be dominated by Brazil's Antonio Tenorio. Team GB begin their 2012 Football 7-a-side campaign with a side that includes former Everton Academy player Michael Barker, top scorer at the 2011 World Championships. In Track Cycling, watch out for Britain's Anthony Kappes who, at 9.30am, aims to repeat his Beijing gold in the B 1km time trial, and for New Zealand's Paula Tesoriero, who broke the women's 500m time trial world record at the Games four years ago.
