World Cup 2018: Josh Magennis injury concern for Northern Ireland

Charlton Athletic striker Josh Magennis is an injury doubt for NI

Charlton Athletic striker Josh Magennis is an injury concern for Northern Ireland's World Cup qualifier against Norway at Windsor Park on Sunday.

Magennis tweaked a hamstring which has prevented him from training this week and his fitness will be monitored.

Sheffield United defender Daniel Lafferty was called into the squad for the crucial game in Belfast on Monday.

The 27-year-old left-back made his international debut in 2012 and has won 13 caps for his country.

Lafferty adds to manager Michael O'Neill's defensive options for the Windsor Park match in Belfast.

Northern Ireland lie second in Group C, five points behind Germany with two wins for their four qualifiers.

Norway are in a disappointing fifth place, having picked up just three points from four games.

O'Neill is without Will Grigg for the Norway encounter after the Wigan Athletic striker was ruled out with a knee injury.

Shane Ferguson is also an absentee, with the versatile Millwall player serving a suspension.

Northern Ireland's 3-0 friendly defeat by Croatia on 15 November brought to an end a 10-game unbeaten home record, O'Neill's side having previously won eight and drawn two at Windsor Park, conceding only three goals in the process.

Their last loss in a home competitive fixture was a 4-2 defeat at the hands of Portugal in a World Cup qualifier in September 2013.

Goalkeepers: Michael McGovern (Norwich City), Alan Mannus (St Johnstone), Roy Carroll (Linfield)
