Swansea City striker Stephen Dobbie has been ruled out of the next two games because of an ankle injury.
The Swans had feared a longer lay-off after watching Dobbie hobble off during Saturday's 3-1 defeat at Norwich City.
He left the ground wearing a protective boot, but two scans have found no ligament damage.
"Stephen has contusion [bad bruising] and swelling around the ankle joint,'' said Swansea's head physio Kate Rees. "Fortunately it is nothing serious.''
Dobbie, whose only start in the Premier League this season came in the opening defeat at Manchester City, will miss Saturday's trip to face Wolverhampton Wanderers and the home match against Bolton Wanderers a week later.
Centre-back Caulker, on a season-long loan from Tottenham Hotspur, had been ruled out until late November with knee cartilage damage, but the 19-year-old is hoping to return sooner.
He has started training with Spurs and could return to Swansea within the next seven days.
"If everything goes well, I will get two weeks of training under my belt with Swansea and then I will be up for selection," he told Swansea's website.
"Fingers crossed that everything goes well because my comeback can't come quickly enough."
