Shane Duffy for Blackburn away to Cardiff in 2016/2017, with 2 own goals and a red card we lost 2-1. 4 days earlier we lost 3-0 away to Wigan with their 3rd goal another Duffy own goal. So 3 consecutive goals across 2 of our matches were Duffy own goals.
Zat Knight produced one of the worst all round performances I’ve ever seen, for Fulham against us at the Cottage in 2004/2005, with non-stop terrible defending and numerous blunders including for our first goal, very nearly scoring an own goal, then getting giving away the penalty for our second goal and getting sent off with a handball.
