Several worries for Di Canio

Swindon boss Paolo Di Canio has several injury concerns ahead of the visit of Leyton Orient.

The Robins will definitely be without Gary Roberts and Giles Coke through injury, while defender Troy Archibald-Henville is rated doubtful at best.
Matt Ritchie is also a doubt with a hamstring injury, but striker James Collins is expected to return after missing the Robins' midweek loss to local rivals Oxford United in the Johnstone's Paint Trophy.
Di Canio must decide whether to return Collins alongside summer signing Andy Williams up front or drop the former Yeovil man to the bench.
Williams, fifth top scorer in League One last season with 16 goals, is yet to open his Town account since moving from the Glovers.
