This is what we know about Allan Saint-Maximin's injury as Steve Bruce 'fears the worst'

The Newcastle United winger left the stadium on crutches after suffering a hamstring injury late in yesterday’s 2-1 win over Southampton.

Saint-Maximin, troubled by hamstring problems early in the game, was asked how it felt by a journalist in the post-match mixed zone.

The 22-year-old – who Bruce said had been “tired” after Thursday night’s 2-0 win over Sheffield United at Bramall Lane – replied with an expletive. He also confirmed that it was his hamstring – and added that it could be a “bad one”.

United’s medical staff will assess Saint-Maximin’s injury today, but head coach Steve Bruce “fears the worst”.

“He’s been so crucial to us,” said Bruce. “Nothing really changes with Allan though, he’s that maverick free spirit which we’ve got to manage.

“He wanted to play, to be fair to him, even though he was hobbling around on his ankle the other night (at Bramall Lane). But when he pulls up the way he did, then we all fear the worst. That is the downside of playing somebody tired.”

Saint-Maximin, signed from Nice in the summer, pulled up in the last couple of minutes after sprinting upfield – and his expression told its own story.

“We don’t know how serious it is,” said Bruce. “He was the big one (injury concern), he obviously hadn’t recovered, but then again he’s always a bit like that. I’ll kick myself if it is a long time. The way he pulled up (wasn’t great), but let’s hope it’s not too serious.”
