Harlequins boosted their Premiership play-off hopes by defeating league leaders Northampton Saints 41-32 at Twickenham on Saturday.
However, the victory was not without controversy as Danny Care was lucky to avoid a red card in the Big Summer kick-off.
Kea appeared to miss his foot and knock the ball over at the breakdown and had already been given a yellow card, but referee Karl Dixon ruled this was just a penalty.
Kea was immediately substituted and his replacement, Will Porter, was the player who scored consecutive tries in the final 20 minutes to seal victory for the home side.

Courtney Rhodes earned a bonus point for the Saints, but Jarrod Evans converted a penalty on the final kick of the game, meaning they could not finish the game without a bonus point.
Harlequins burst out of the blocks and Marcus Smith hit a pinpoint cross-field kick into the hands of Luke Northmore and over the goal line. He scored within the first three minutes.
Marcus Smith missed the conversion and soon after Kea was guilty of a head-on collision with Laws, reducing Quins to 14 men.
Quins tried and missed a penalty just before Kea returned to the field, but Northampton scored a try on the counterattack, Tom Litchfield chipping over the top and Ollie Slightholm collecting and scoring.
Finn Smith converted and immediately added a penalty to his team's score with a great strike from long range.
Harlequins weren't behind for too long, however, as Northmore raced through the gap to score his second try and Marcus Smith converted to make it 12-10.
Andre Esterhuizen's knock-on from the restart set Northampton up in attack, and after Louis Reiner was sin-binned for a deliberate knock-on, Finn Smith put his side back in the lead with a penalty.
However, Quins took a corner kick and held out until Stephen Lewis scored.
Saints thought they had scored when Sam Graham extended his arm and grounded the ball out, but a knock-on from Alex Mitchell in the build-up had the try called off.

Quins rubbed salt into the wound six minutes into the second half with Kaydan Marley cantering, but Northampton canceled out the effort when George Firbank scored a timely goal off an inside pass from James Lamb.
After 62 minutes, Northampton were upset that Kea was sent off to play Mitchell inside Quins' 22, causing a huge controversy, but the Quins player was immediately substituted to avoid a second yellow card.
Saints took advantage of the penalty with Lichfield charging in and Finn Smith scoring the try to give his team the lead.
However, after Tyrone Green returned from the bottle, Care's substitute Porter gave Quins two more points, and Northampton earned a try bonus point through Laws.
Evans had the final say on the penalty, costing the Saints a bonus point for the loss.
