Chris Wood and Noni Madueke scored as Chelsea and Nottingham Forest played out a tactical and feisty draw at Stamford Bridge.
Forest went ahead when 32-year-old striker Wood slid in a finish past Robert Sanchez after a good set-piece routine involving James Ward-Prowse and Nikola Milenkovic in the 49th minute.
But Chelsea responded quickly as Madueke equalised eight minutes later after cutting in on his left foot and shooting, his fourth such effort having had the beating of left-back Alex Moreno.
Midfielder Morgan Gibbs-White came off injured in the second half – putting his chances of contributing with England this month in major doubt as he gingerly walked off the pitch, looking in pain and frustrated.
Referee Chris Kavanagh sent off Forest’s Ward-Prowse for deliberately handling the ball to stop a Nicolas Jackson counter-attack in the second half, giving him a second yellow card, having booked him earlier on for a more conventional tactical foul on star man Cole Palmer.
Then, Madueke also appeared to go off injured after a melee sparked by Neco Williams, who pushed defender Marc Cucurella into Chelsea manager Enzo Maresca.
Chelsea looked to their extensive bench to win the match, bringing on Christopher Nkunku, Joao Felix, Mykhailo Mudryk and Pedro Neto to win the game with a man advantage, but Palmer had two chances well saved by Matz Sels and Felix headed an effort wide in stoppage time.
There were two huge efforts saved in the closing minutes.
Williams curling effort for the visitors was saved by Sanchez, before – at the other end – Nkunku’s diving header was saved at close range by Sels.
It felt like a close match of two in-form clubs pitting their records against each other, with Chelsea dominant in the latter stages.
The Blues’ five-game winning run has ended but they remain unbeaten in the league since the opening match of the season, while Forest are undefeated on the road in six matches, their longest such run since 1995.
