2012–13 Premiership Rugby

The 2012–13 Aviva Premiership was the 26th season of the top-flight English domestic rugby union competition and the third one to be sponsored by Aviva. The reigning champions entering the season were Harlequins, who had claimed their first title after defeating Leicester Tigers in the 2012 final. London Welsh had been promoted as champions from the 2011–12 RFU Championship, their first promotion to the top flight.

Summary
Leicester Tigers won their tenth title after defeating Northampton Saints in the final at Twickenham, having finished second in the regular season table. London Welsh were relegated, in part, for having received a 5-point deduction for fielding a player who did not hold an Effective Registration. It was the first time that London Welsh had been relegated from the top flight since they first achieved promotion.

As usual, round 1 included the London Double Header at Twickenham, the ninth instance since its inception in 2004.

Rule changes
For the second consecutive season, significant changes were made to the Premiership's salary cap. Last season, "academy credits" were introduced, giving each team a £30,000 cap credit for each of up to eight home-grown players in the senior squad. This season, the team cap rose for the first time since the 2008–09 season when it was increased from £2.2 million to £4 million. The new cap is £4.26 million before academy credits and up to £4.5 million with credits. In addition, each team was allowed to sign one player whose salary did not count against the cap.

Teams
Twelve teams compete in the league – the top eleven teams from the previous season and London Welsh, who were promoted from the 2011–12 RFU Championship to the top flight for the first time. They replaced Newcastle Falcons, who were relegated after fifteen years in the top flight.

Pre-season
Following a lengthy appeal, London Welsh successfully gained promotion to the Premiership, having contested the Professional Game Boards recommendation to refuse them entry based on the Minimum Standards Criteria. This meant that Newcastle Falcons were relegated, following their confirmation that they would not appeal the new decision.

The 2012 edition of the Premiership Rugby Sevens Series began on 13 July 2012 at The Stoop, continued on 20 July at Edgeley Park, and 26 July at Kingsholm. This was the first opportunity of the season for any of the teams competing in the Premiership to win a trophy. The finals were held on 3 August 2012 at The Recreation Ground, and the Series was won by London Irish.

Regular season
Premiership Rugby announced the fixture list on 4 July 2012. As with previous seasons, Round 1 included the London Double Header at Twickenham.

Round 22
All games in Round 22 kicked off at 15.00 on 4 May 2013, so as to not give any team a potential advantage with regards to knowing how to achieve a play-off berth, Heineken Cup place, or safety from relegation.

Play-offs
As in previous seasons, the top four teams in the Premiership table, following the conclusion of the regular season, contest the play-off semi-finals in a 1st vs 4th and 2nd vs 3rd format, with the higher ranking team having home advantage. The two winners of the semi-finals then meet in the Premiership Final at Twickenham on 25 May 2013.

Final
The final was contested at Twickenham on 25 May 2013 between Leicester Tigers and Northampton Saints with Leicester winning 37–17. Northampton captain Dylan Hartley was sent off for using foul and abusive language just before half-time after calling referee Wayne Barnes a "f*****g cheat". This was the first time a player has ever been red carded in a Premiership Final, as was said by the commentators during the match.
