The defender missed Wigan's 4-0 defeat to Manchester United with a groin injury picked up on international duty for Paraguay but is targeting a comeback against the Cottagers
The centre-back was forced to sit out Saturday's 4-0 loss to Manchester United at Old Trafford after picking up a groin injury during Paraguay’s loss to Venezuela.
However, he is keen to make his comeback when Roberto Martinez's men host the Cottagers, but has conceded the club’s doctor will have the final say.
"I'm OK," he told reporters. "I'm waiting to hear back from the doctor, but my hope is that it won't be a long-term problem.
"I'm feeling better all the time, although there is still a little bit of pain there.
"It was a pretty normal movement during the game, and I just felt pain in the muscle. I came off straight away because I didn't want to make it worse.
"I obviously want to play on Saturday, but the decision will be up to the doctor."
Wigan currently sit in 14th place in the Premier League after taking four points from their opening four matches.
