Team GB has claimed another rowing medal, with two brothers from Northern Ireland missing out on gold by inches.
In an agonisingly close race, the lightweight men's four made it a second day of success on the water at Eton Dorney.
On Wednesday rowers Helen Glover and Heather Stanning won the first British gold of the Games, becoming overnight celebrities.
Richard and Peter Chambers, who grew up in Coleraine, along with Rob Williams and Chris Bartley won Great Britain's fourth silver. Their success followed the rowing victory in the women's pair, and cyclist Bradley Wiggins making history by winning the men's time trial.
Richard Chambers said: "That was brutal, really, really brutal. We were just fighting and fighting just to get ourselves back in contention and we did a cracking job. To even get the silver was impressive from where we came from.
"(We) struggled to keep to the pace of the three crews on the left-hand side in the first quarter of the race but we just dug our heels in and fought really hard."
Struggling to hide his disappointment, Williams said: "We wanted to win. A silver isn't fantastic but it's a medal at the Olympics and you've seen the event: you can't walk into it and expect to get anything.
"We wanted to win but there isn't just two crews. It's not like we could have been three lengths back and got the silver.
"We have to be happy to get a medal - these are a home Olympic Games and we're silver medallists, it's not terrible. It's a shame we didn't win - we really wanted to win. But what can you do? We did everything we could."
