The Newcastle United striker was given oxygen as he was carried off the field in Saturday's 1-1 draw against Birmingham City.

Mitrovic had suffered a badly gashed leg in the build-up to Daryl Murphy's goal in the third-round FA Cup tie.

There were fears the Serbia international had suffered a break or ligament damage.

But the 22-year-old could be back playing in a matter of weeks.

"The cut is major, but I feel good," Mitrovic told Blicsport. “Thank God it looks like the ligaments and knee are fine.

"However, I expect additional examinations. We have to be sure that there is no damage to the knee.

“The first forecasts are that I will not be on the pitch for three or four weeks. The cut is just in an inconvenient spot.”

Blicsport have published a graphic image of the cut, which was inflicted by the studs of goalkeeper Adam Legzdins as he attempted to block Murphy's fifth-minute shot.
