Newcastle United stretched their unbeaten run to seven games but were frustrated after West Ham United's late equaliser at the London Stadium on Sunday afternoon.
Eddie Howe's side looked to be on their way towards a fourth successive Premier League win after Alexander Isak's second-half brace.
But Mohammed Kudus' late strike ensured that the Hammers would take a point from the final game before this month's international break.
Howe made one change from the incredible 4-1 demolition of PSG in midweek, as Elliot Anderson came in for the suspended Anthony Gordon, who was a big miss in the first half.
David Moyes' side started on top and deservedly took the lead on eight minutes when Emerson rounded Nick Pope after a lovely through ball from Lucas Paqueta, before squaring for Tomas Soucek for a simple finish into an empty net.
The turning point perhaps came a few minutes later, when just moments after picking up his first yellow card, Bruno Guimaraes scythed down James Ward-Prowse on the halfway line, but he escaped an early bath.
The Toon came out much stronger in the second 45 and were gifted an equaliser when Kieran Trippier's free-kick was headed into Isak's path by Nayef Aguerd, with the Swedish forward providing the finish for 1-1.
On 62 minutes, it was 2-1, with Trippier once again the provider as his volleyed cross found Isak at the back post for a tap-in.
The former Real Sociedad forward could have had his hattrick after rounding Alphonse Areola, but he was forced wide and his effort came back off the post.
Newcastle were made to pay for that miss with just one minute of normal time remaining, as Vladimir Coufal surged forward and found Kudus on the edge of the box, with the substitute taking one touch before smashing past Pope for his first Premier League goal.
Howe admitted in his post-match interview that Newcastle were perhaps suffering from a 'hangover' after the PSG result, but his side now have two weeks until their next league game against Crystal Palace at St James' Park on Saturday, October 21.
