Sami Hyypia has been frustrated by Sheffield Wednesday in his first game in charge of Brighton & Hove Albion as the visitors go into the half-time break leading 1-0.
The game began in a rather scrappy manner and Jake Forster-Caskey was booked in the 10th minute for a late challenge.
Brighton's best chance of the half fell the way of Kazenga LuaLua after good work by Chris O'Grady, but Kieren Westwood saved well.
Brighton's Shamir Fenelon fired a shot towards goal, but Westwood was also equal to his effort.
Sheffield Wednesday rarely threatened in an attacking sense, but a moment of quality from Giles Coke gave the visitors the lead shortly before the break. The midfielder struck a long-range effort with his left foot which curled beyond the reach of David Stockdale.
