Mark Warburton says the Glasgow Rangers hitman should be back at Ibrox sooner than expected.
The 26-year-old hitman has been out of action since falling injured in Rangers' 1-1 draw with Hamilton in the first Premiership game of the season.
Warburton initially revealed that Waghorn could be out for up to a month in a prognosis which jeopardised his involvement in the visit to Celtic on September 10.
But the 53-year-old boss has now said that his talisman - who was running in training on Monday - should definitely be back sooner than expected.
“Waggy has made great progress and credit to him and the medical team," he told the club's official website.
“He is out jogging and they will gradually increase the loading, we won’t welcome him back too soon but he is certainly way ahead of the curve."
Waghorn is vital for Rangers this season and the Gers supporters will be delighted with the latest development.
Speculation has mounted from The Scottish Sun that Preston hitman Joe Garner is set to join up with the Ibrox club this week, but Waghorn will certainly remain Rangers' go-to-guy in the goalscoring stakes.
Joe Dodoo might lead the line at the expense of Kenny Miller - who did score in Saturday's 2-1 win at Dundee - when Warburton's side host Motherwell this Saturday.
