Peterborough United have signed defenders Ben White and Daniel Lafferty on loan from Brighton & Hove Albion and Sheffield United respectively.
Both players have joined the League One side until the end of the campaign.
White, 21, spent last term on loan with Newport County and has featured for the Seagulls' Under-21 side in 2018-19.
Seagulls boss Chris Hughton said, “This move is one which allows Ben to play regular first-team football at a good level for his development. At this stage of his career it's important that he continues to gain as much match experience as possible.
“He's someone who we've had around the first-team squad for the first half of the campaign, but with competition for places increased with the return of Dan Burn from Wigan, this gives him the chance to go out and play regular football at a level higher than he experienced last season."
