Chris Wood scored a hat-trick on his return to St James' Park as Nottingham Forest ended a seven-game winless run with a stunning Premier League victory at Newcastle.
The result moves Forest up to 16th in the table and five points clear of the bottom three prior to Tuesday's other fixtures.
Alexander Isak had seemingly put Eddie Howe's side in control when he stroked home a penalty midway through the first half after going down under a challenge from Ola Aina.
But Newcastle only sporadically threatened in attack and always looked vulnerable to a rejigged Forest side set up to counter-attack at pace.
