While O'Donnell and Stevenson leave on loan
The Town have loaned defensive trio Alfie Mawson, Joe Davis and Pelly Ruddock from Brentford, Port Vale and West Ham respectively.
All three players have made their senior debuts for the parent clubs and arrive at Kenilworth Road until 4th January.
Commanding centre-back Mawson, 19, joined Brentford from Reading in 2010 and made his debut for the Bees in their Carling Cup tie with Derby this season.

The defender has recently enjoyed a loan spell with Maidenhead United but cannot make his Town debut at Staines having already featured in the FA Trophy this season.
However, 20-year-old Davis, is eligible to feature for the Hatters at the weekend. The defender is the son of Crewe manager Steve, and he made his debut for Vale when aged just 17 in the 2010/11 campaign.

Burnley-born Davis was named the Valiants’ Young Player of the Year in 2012 and has made 19 appearances in all competitions for Micky Adams’ side, including eight appearances last season as Vale won promotion via third place in League 2.
Meanwhile 20-year-old Ruddock, who can also play in midfield, made his debut for the Hammers in a Carling Cup tie this season having originally signed for the East London club from Boreham Wood in 2011.
Ruddock played against the Town in the development squad match between the two clubs at Kenilworth Road last month and has scored twice in nine Premier League Under-21 division games this season.
The Hatters have no fit centre-half to face Staines on Saturday with Steve McNulty, Andy Parry, Alex Lacey and Anthony Charles all unavailable through injury.
The Town have also loaned two players from Kenilworth Road to two clubs in the Skrill Premier.
JJ O’Donnell has joined Hyde and Jim Stevenson has been loaned to Dartford. The pair will remain at those clubs until 4th January and both are eligible to play in the FA Trophy this weekend.
Hyde take on North Ferriby United whilst Darford entertain Forest Green Rovers. We wish JJ and Jim the very best of luck on their time out on loan.
