Luton defender Steve McNulty has signed a new contract with the club.
Owen Garvan is expecting to leave Crystal Palace this summer and claims to have a number of options to consider.
Sky Bet make Martin O'Neill the odds-on favourite to replace Giovanni Trapattoni as Republic of Ireland boss following Giovanni Trapattoni's sacking.
O'Neill was installed as the 5/6 favourite for the job on Wednesday morning with Trapattoni's exit widely anticipated and by the end of Wednesday those odds were 8/11.
Leeds boss Brian McDermott had been considered a lively outsider at 16/1 but has since been cut to just 6/1 while Mick McCarthy (10/1), Roy Keane (18/1) and Chris hughton (28/1) are other possible alternatives.
Sky Bet Football Trader Chris Spicer said: "O'Neill seems the obvious choice given his experience and availability and our punters tend to agree, with all the early money coming for him despite the short odds."
