The goalkeeper had precious little to do in the opening 45 minutes despite Hull hitting the woodwork twice, but held on well to prevent Upson netting an own goal. Came out well to collect crosses after the break, but was beaten low by Sagbo late on.
The athletic centre-back put in a number of strong aerial blocks in a towering performance, with a diving header to stop a Figueroa cross a first-half highlight. Will be disappointed to be beaten by Sagbo for the equaliser though.
The left-back was beaten on a number of occasions by the marauding El Mohamady, and wasted possession too often after being pole-axed by Davies while scything down the Egyptian for a yellow.
The veteran marshalled the back line well alongside young Dunk, and was alert to the threat of Sagbo. Showed a resolve that will stand his side well for the rest of the season.
The former Chelsea youth player excelled against experienced opposition showing good strength early on while distributing the ball cleverly. The powerful midfielder will surely have top-flight suitors this summer unless the Seagulls are promoted.
The 32-year-old captain showed tenacity getting forward down the right to put in crosses, while he was alert to the danger going the other way. An experienced showing.
Back for his first start of 2014 after a hamstring injury layoff, the striker was energetic up top, providing a neat assist for Ulloa while the Argentine should have nodded in Buckley's cross before half-time. Replaced at the interval.
The defensive midfielder did a solid job in the middle to subdue the Tigers' attacking threats from deep.
The winger drifted along the front line and teased from the left but didn't have the same impact as other Seagulls. Replaced late on.
The 19-year-old was alert from the off and moved the ball about well for the Seagulls, and delighted the fans with an early bicycle kick attempt. A strong presence throughout, he typified his side's enthusiasm and work rate and saved his side at the death.
The Argentine started brightly providing a presence up front, and scored a lovely dinked finish after breaking through on 30 minutes, but missed a sitter of a header on the stroke of half-time Replaced with 13 minutes to go for Obika, but that miss proved costly.
The Scot was given no help by his defence for Ulloa's opener, but perhaps could have stood up a little longer, and had few saves to make throughout.
The left-back put in a couple of decent balls from the left but struggled to deal with with the overlapping runs of Calderon. He failed to show his usual tenacity.
Strong in the air but let Ulloa slip by too easily for the opener, and was fortunate the Argentine headed wide when unmarked. Subbed off for Boyd.
The centre-back went close with a strong header off the bar after Brighton's opener, and covered well - though will not want to see Ulloa's goal again.
Ahmed El Mohamady
The Egyptian flew down the right flank and looked a real danger for the visitors, with his pace troubling Chicksen into a booking while he went close on the hour.
Toiled in the channels and provided an outlet on the wings but was afforded precious little reward. Replaced by Fryatt.
The 24-year-old forward tried cute passes early on that weren't picked up on by his team-mates as he drifted in and out of proceedings. Booked for a foul on Lua Lua.
The Tigers playmaker was his usual dependable self in possession, though was overrun in the early stages by a vibrant Seagulls side. Was wasteful with his set-pieces.
Livermore was quieter than usual as Brighton enjoyed possession in the centre, and like Huddlestone he struggled when the Seagulls broke forward.
The Tigers captain provided a fine cross for Sagbo's early effort off the bar, but was otherwise quiet and get cautioned by the lively March.
The Ivorian was unlucky not to score with an acrobatic volley that crashed off the bar after 20 minutes, and was a lurking menace for the Tigers. Got the vital equaliser with four minutes to spare with a clinical finish.
