Bristol City will check on the fitness of striker Alvaro Saborio before they entertain Peterborough at Ashton Gate.

Saborio played for Costa Rica on Wednesday night and only arrived back in Bristol on Friday, so manager Gary Johnson will assess his condition before making a decision.

If Saborio does not start, David Clarkson, Danny Haynes and Ivan Sproule will all be hopeful of partnering Nicky Maynard in attack, with Clarkson impressing against Bournemouth's reserves on Tuesday.

Defender Lewin Nyatanga will also be checked over after playing for Wales in Liechtenstein on Wednesday.

Liam Fontaine is definitely out as he battles with an ankle injury that is likely to sideline him until the end of the month, while Christian Ribeiro suffered a recurrence of a groin injury while on duty with the Wales Under-21 squad.

Defender Brian Wilson is also set for a lengthy spell out after fracturing his shin bone and midfielder Frankie Artus has joined Cheltenham on loan for a third time.

Tom Williams is a major doubt for Peterborough ahead of their trip.

The midfielder is poised to have a fitness test on an ankle injury which he picked up in training.

Should Williams be ruled out, Jamie Day is pushing for a recall after playing an hour in the club's reserve side on Wednesday.

Manager Darren Ferguson is definitely without the services of midfielder Paul Coutts, who is out for two to three weeks with a foot problem.

Centre-half Craig Morgan is expected to start despite being on international duty for Wales in midweek.

Highly-rated George Boyd has been told he will start by Ferguson and the striker will equal Eric Steele's record of 124 consecutive Football League appearances for Posh.
