Northern Ireland forward Kyle Lafferty's groin injury 'not serious'

Northern Ireland manager Michael O'Neill has calmed concerns over Kyle Lafferty's groin injury ahead of their Euro 2016 opener against Poland this Sunday.

The Norwich City striker limped out of training on Tuesday morning and sought immediate treatment.

It is believed that the 28-year-old overstretched while trying to reach a loose ball, but O'Neill has insisted that the problem is not serious.

"He's fine, it was precautionary," O'Neill told reporters. "There are no major concerns there. It was a little twist but on examination we don't expect any issues at all."

After facing Poland on June 12, the team will take on remaining Group C contenders Ukraine and world champions Germany.
