Swindon Town boss Mark Cooper has revealed that Troy Archibald-Henville has undergone a knee operation.

The defender, who has played just eight times for the Robins since joining in June 2012, had recently been on loan at Carlisle United.

"Troy's had an operation on his knee so he's not going to be in our thinking for the foreseeable future," Cooper told the Swindon Advertiser.

Archibald-Henville will not return until 2014, but could play a part before the end of the campaign.
