Colchester have signed former Yeovil midfielder Joe Edwards, subject to paperwork.
Southampton have announced the signing of versatile defender Cuco Martina from FC Twente on a two-year-deal.
Nikica Jelavic insists he has a "great opportunity" at Hull after the club completed the record signing of the Croatian striker from Everton.
The Tigers announced the signing of the 28-year-old on a three-and-a-half-year deal and it is expected manager Steve Bruce will hand him his debut in Saturday's Barclays Premier League match at Norwich.
The club said the fee was undisclosed, but it is understood to be £6.5million rising to £7.5million if they stay in the Premier League.
Jelavic said: "As soon as the manager called me I realised straight away that he was really interested in signing me and that it is a great opportunity for me to come here.
"It is a good club, and we have a good squad. We talked a little bit, but it didn't take long to realise that it was right for me.
"It's a newly-promoted club, but I can see straight away that there is a lot of ambition here within the club and I hope that we can build on the great start to the season and become a really strong Premier League team over the coming years."
Jelavic played for Hajduk Split and Rapid Vienna before moving to Rangers, where he scored 36 goals in 54 games.
He then moved to Everton where he hit 21 goals in two years but saw his form tail off last season and has struggled to secure a starting place this term.
