Luton have signed former Peterborough and Brighton striker Craig Mackail-Smith on a two-year deal.
Norwich City have completed the signing of goalkeeper Jake Kean following his release from Blackburn Rovers.
Paolo Di Canio has emerged as Sky Bet's 9/4 favourite to be the next Swindon manager despite only vacating the position on Monday evening.
The Italian handed in his notice due to off-field problems with the League One club's sale failing to be confirmed, but is now being backed for a very quick return to the County Ground..
Di Canio's former assistant Fabrizio Piccareta has been placed in temporary charge but is 12/1 to take the post on a permanent basis, while Mike Newell is 4/1, Dave Hockaday 7/1 and Paul Bodin 12/1 having attracted some backing.
Sky Bet Football Trader Chris Spicer said: "We initially went out without Di Canio our list of candidates, with Mike Newell and Dave Hockaday leading the betting, but were seeing little interest in the market.
"However, we then added Di Canio at 5/1 by request this afternoon and the Italian has attracted almost all of the interest ever since."
