JONJO Shelvey is expected to wear a cast against Saints this weekend – after breaking a finger in a training ground bust-up.

The Newcastle United midfielder fractured a finger bone after turning peacemaker during a heated exchange between Jamaal Lascelles and Mo Diame,

The punch up began when defender Jamaal Lascelles accused Diame of being ‘lazy’.

Shelvey, who has played three games since returning from a ban for his red card against Spurs on the season’s opening weekend, is being monitored ahead of Newcastle’s visit to St Mary’s on Sunday.

When asked about the Diame-Lascelles incident, Newcastle’s Spanish forward Ayoze Perez played down the bust-up.

“I’m not going to comment anything about that. It is something that happens with every English team,” Perez insisted.

“We have a great dressing room, a great spirit and that is nothing important. We are not going to comment on that.”

Shelvey, 25, has twice finished on the losing side at St Mary’s since scoring a late winner for Swansea City in February 2015.

Former Nottingham Forest defender Lascelles recently signed a new contract which keeps him at Newcastle until 2023.

Senegalese midfielder Mo Diame is in his second season with Newcastle following his move from Hull City 14 months ago.

l Gordon Strachan and the Scottish FA are expected to take some time to consider the Scotland manager's future after their World Cup near-miss.

The former Saints manager’s contract expires next month following Scotland’s failure to reach the play-offs on goal difference after a 2-2 draw in Slovenia.

It is understood there was no debrief scheduled between the two parties in the immediate aftermath of the Ljubljana encounter.

A late Robert Snodgrass equaliser ensured Scotland remain unbeaten this year - a run which includes the final six matches of their qualifying group.

Former Scotland striker Kris Boyd believes Strachan will himself call time on his international reign.

“I think he will leave of his own accord,” the Kilmarnock player said. “The SFA would want him to stay, they will appreciate the job he has done, but the criticism Gordon received in the early part of the campaign, he won’t have forgotten about.

“He is the right man for the job, you only need to see the way it has been turned around.

“A lot of people say that at the start of the campaign he was a bit pig-headed and not wanting to change things, but that’s the way Gordon has been throughout his career and it has brought him success.”
