Chris Martin's 45th-minute strike proves enough to secure a slender 1-0 lead over Middlesbrough, with Curtain Main sent off for the visitors.
Ten-man Middlesbrough have fallen behind to Derby County on the stroke of half time, courtesy of Chris Martin's 45th-minute strike.
Curtis Main was given his marching orders shortly after the half-hour mark for a second bookable offence following a late challenge on Jake Buxton.
Prior to that the visitors looked the better of the two sides, as Kei Kamara saw an audacious overhead whistle narrowly past the post.
Following the dismissal of Main, the Rams looked intent to capitalise on their numerical advantage, as Martin fired the hosts into the lead moments before the interval.
