Newcastle United midfielder Jonjo Shelvey broke his finger in a training ground bust-up, it has been revealed.

The Sun says Shelvey has suffered a broken hand splitting up a training ground fight between Toon teammates Jamaal Lascelles and Mo Diame.

England international Shelvey has recently returned from suspension after his red card on the opening weekend of the season against Tottenham.

But the former Swansea man could now be set for another spell on the sidelines after jumping in between skipper Lascelles and Diame, according to The Sun.

The pair apparently traded punches before Shelvey muscled in, allegedly leaving the 25-year-old's left hand in a cast.

Shelvey is set to be monitored by medical staff ahead of the Magpies' trip to Southampton on Sunday week.
