Swansea City boss Brendan Rodgers has admitted captain Garry Monk could miss the start of the Premier League season.
Monk, who is set to be offered a new deal, did not feature in either of the Swansea sides who faced Port Talbot and Neath in friendly matches on Saturday.
The 32-year-old defender picked up a foot injury during the closing weeks of last season.
"The likelihood is he may not be fully fit for the beginning of the season," said Rodgers.
"It goes back to the end of the season. He'd done remarkably well to play in the play-off final.
"He had injections and all sorts of jabs to get him through and in the off season he's just rested it.
"He can't do much impact work on the field. He's doing the work with the medical team and they're looking after him very well."
The Swansea boss refused to be drawn on reports the club have made a bid of approximately £1m for Nottingham Forest keeper Lee Camp.
BBC Wales Sport understands the Swans have made an offer to Forest for the Northern Ireland international having failed in their attempts to sign Fulham's David Stockdale.
"It's disrespectful if I talk about Lee Camp," said Rodgers. "He's a Nottingham Forest player.
"There's a number of goalkeepers on our radar and all we want to do is take our time and make sure we get the right one and the right deal for the football club."
In a game which kicked off at lunchtime at the Gnoll, they were beaten 1-0 by Neath before later defeating Port Talbot 3-1 at the Genquip Stadium.
But Rodgers did not put too much emphasis on the results and added they had been useful exercises.
"I think the most important things was the players got their geography of the pitch again," said Rodgers.
"We've only been back a few days and the most important item out of the two games was for the players to improve their fitness and to make sure we had no injuries.
"I think it's very important for the local area, [now] we're a Premier League club, they don't feel too detached.
"It's important we promote the club in the right way and support two of the local sides."
