Leeds have appointed former Leicester manager Rob Kelly as the club's new assistant head coach on a two-year contract.
Leon Britton admits he may be forced to leave Swansea this summer in search of regular first-team football.
The 31-year-old Scotland international moved to Wanderers on an initial one-month emergency loan on September 27 but he will now remain at the Reebok until after Christmas.
Bolton are unbeaten in four Championship games with McNaughton in their side with three draws and a 2-1 win at Birmingham during October.
McNaughton signed a new one-year contract with Cardiff during the summer and is the club's longest serving player after joining them on a free transfer from Aberdeen in May 2006.
However, he failed to make it into the Bluebirds' Premier League team at the start of the season and made only two appearances in the Capital One Cup prior to his loan switch to Bolton.
