Preston North End defender Craig Morgan has joined the injured list at Deepdale.
The centre-half underwent hernia surgery yesterday.
Morgan is one of the six players who has been training at Accrington and Rossendale College, as they wait for their Deepdale futures to be resolved.
The others are Iain Hume, Jamie Proctor, Danny Mayor, Adam Barton and Keammar Daley.
Paul Coutts and Conor McLaughlin were in that group before leaving to join Derby and Fleetwood respectively.
Morgan, 27, who was a £400,000 signing from Peterborough two years ago, is among the highest wage earners at North End.
He didn’t feature a great deal in the first team after Westley’s arrival, partly due to injury and then falling out of favour.
But he returned to the side for the final four games of last season.
The hernia operation and recovery is expected to keep him sidelined for around three weeks.
Recent signing Lee Trundle, is also currently facing a spell on the sidelines.
He damaged his right knee in Saturday’s defeat at Morecambe, and PNE are awaiting scan results.
North End boss Graham Westley said: “It was a nasty one and the early signs aren’t that positive.
“It could be four weeks, it could be longer.
“We are probably not looking at something which would keep him out for three months for example.
“But it could be a four-to-eight weeks thing.
“It was a twist of the knee and there are all sorts of structures in there which are possibilities.
“He’s having it scanned and we’ll be able to talk more accurately then.”
Trundle only signed a 12-month contract the afternoon before the Morecambe game after a successful trial period.
The 35-year-old netted in last week’s friendly against Chorley.
Meanwhile, North End have merged their ticket office and retail operation at Deepdale.
During the week, ticket sales will be made in the club shop.
The ticket office in the Sir Tom Finney Stand will open on the day of all home games, while the Invincibles Pavilion ticket office will open from 1pm for home matches with a 3pm kick-off.
