Arsenal's Welbeck ruled out of pre-season tour with knee injury

Danny Welbeck is already out with an injury.

The oft-injured Arsenal forward has been ruled out of the team's upcoming trip to Signapore after suffering a setback in the same knee that kept him out during the final months of last year's Premier League campaign

Welbeck has been out of action since March when he suffered a bone bruise during a training session with the English national team.

He joins Thomas Rosicky as an absentee following the midfielder's failure to overcome a knee injury suffered in Czech Republic's match against Iceland in June.
