Wigan have signed veteran defender Alex Bruce and 21-year-old winger James Weir from Hull on loan until the end of the season.
The duo become Wigan's second and third arrivals of deadline day following the signing of goalkeeper Matt Gilks from Rangers for an undisclosed fee.
Latics manager Warren Joyce believes the experience of Bruce, 32, could prove crucial as his team battle to stay in the Championship.
"Alex knows this division inside out, he is street-wise and understands exactly what we need over the next three months. He adds tremendous competition to the squad,'' Joyce said on Wigan's official website.
