Sunderland boss Steve Bruce is anxiously awaiting the results of a scan on top scorer Darren Bent.

Bent pulled up clutching his hamstring late in Saturday's 1-0 win over Arsenal at the Stadium of Light - a match in which he scored the winner - and underwent a scan on Sunday. The England striker, who has scored nine goals in a impressive start to his career on Wearside, is a doubt for this weekend's trip to Wigan and Bruce is hoping he is not set for a longer absence.

He told the club's official website, www.safc.com: "Darren's had a scan and we're waiting for the results. If it is his hamstring, we could be looking at about three weeks out."

He added: "We won't know anything more until the results come back so we will have to keep our fingers crossed."

Bent's absence would leave Bruce with a headache as Kenwyne Jones is suspended after being sent-off against West Ham last month.
