The Seagulls have recalled keeper Christian Walton, 21, from his loan spell at Luton.
A club statement insists it’s a precautionary measure following an injury to Niki Maenpaa.
But it raise questions as to whether Chelsea are set to complete a deal for Stockdale.
The Blues want the former Fulham man as a replacement for Asmir Begovic, who wants to join Bournemouth,
Manager Chris Hughton said, “While Niki’s injury is not as bad as we first feared, he will be sidelined for a short period of time.
“During his period of rehabilitation we will need goalkeeping cover for David Stockdale.
“Christian has been playing regularly at Luton Town and has really benefitted from his time there.
“Ideally he would have continued, but he is now needed back here to ensure we have proper cover in the goalkeeping position.”
Walton has played 33 times for Luton this season, adding to his four senior appearances for Albion, and ten games played on loan during spells at Bury and Plymouth Argyle.
