English 5,000m runner Andy Vernon has apologised to Scotland's Lynsey Sharp after a Twitter row over her winning silver in the Commonwealth Games 800m.
Sharp, 24, finished second in Glasgow on Friday, less than a day after being on a hospital drip because of illness.
Vernon was critical of her reaction to her performance in several comments on the social media website.
But later Vernon, 28, apologised and tweeted: "What started as a joke got out of hand."
After Sharp had written that she planned to buy a Chanel handbag after winning a medal, Vernon said she should "mention it now and again".
But the Scot retorted: "It's not my fault cross country doesn't get quite as much publicity."
The pair then exchanged insults on the social media website, including Sharp referring to Vernon as "Andy Vermin".

|Sharp: "Just remembered I promised myself a Chanel handbag if I won a medal."|
|Vernon "You won a medal? You should mention it now and again."|
|Sharp: "It's not my fault cross-country doesn't get quite as much publicity."|
|Vernon: "Self-publicity isn't quite the same. And I don't use a drip to get my medals."|
|Sharp: "Andy Vermin, I had 5ml of fluid through a drip, about the same volume as one tear I just cried looking at your performances."|
|Vernon: "It's not about who's better. It's about how you use Twitter. Be proud of your medal. You just don't need to tell us every day."|
|Vernon (later): "I will formally apologise to Lynsey Sharp when I see her, but for now please accept my apologies. What started as a joke got out of hand."|
