West Ham midfielder Mark Noble's loan with the Blues has been confirmed. The 19-year-old will join Town for three months from Monday.
Boss Jim Magilton told the club site that he is pleased to have tied up the temporary signing: "I've been trying to get Mark here for a few weeks and we're delighted to have finally sorted things out.
"I spoke to the lad during the week and he's keen to come here, and we're looking forward to having him here.
"With Owen Garvan out for a while, we need other options in midfield and Mark will provide that."
Noble will make his debut against former loan club Hull City in a week's time.
The Hammers have a recall on the England U19 international should they require him in an emergency. The spell could eventually be extended depending on the wishes of the two clubs after the initial spell is completed.
