London - Jonny Wilkinson was at the centre of an injury scare Monday as England gathered for the first time ahead of their autumn international Test series.
The Toulon fly-half will undergo a scan on Tuesday after complaining of soreness in his left shoulder, giving England manager Martin Johnson a potential headache as England prepare to face New Zealand on November 6.
Wilkinson, the hero of England's 2003 World Cup triumph, has been ravaged by injuries since that career highpoint seven years ago.
However the playmaker has been in sparkling form for French outfit Toulon this season which had made him the early favourite to win a starting berth against the All Blacks at Twickenham.
Charlie Hodgson is on standby to replace Wilkinson should he fail to recover in time for the New Zealand match.
Wilkinson is one of five England players nursing knocks as the opening match of the autumn international series looms closer.
Meanwhile, Martin Johnson has called up four players as injury cover.
Harlequins prop Joe Marler, Northampton flanker Tom Wood, Wasps No. 8 Dan Ward-Smith and Saracens' Brad Barritt were all summoned on Monday after the elite squad was hit by injuries.
David Wilson (sore back), Hendre Fourie (bruised ribs) and Wasps pair Simon Shaw and Riki Flutey (both calf) were all hurt over the weekend and are doubts for England's first match of the four-game series - against New Zealand at Twickenham on November 6.
The Rugby Football Union said on Monday the four injured players will be treated and assessed by the England medical team in consultation with doctors from their clubs.
