Kazenga LuaLua has joined Brighton on a permanent basis from Newcastle, having been on loan with the npower Championship side for the first part of the season.
The north-east club confirmed on their website that the 20-year-old winger had signed a three-year contract with the Seagulls and joins them for an undisclosed fee.
He has started just two games since his latest loan spell began, having been on loan twice before to Albion.
Millwall goalkeeper David Forde could face a spell on the sidelines after a recurrence of his thigh injury.
Forde passed a late fitness check on the problem, which forced him to withdraw from the Republic of Ireland squad last week, but lasted only 35 minutes of Sunday's 2-1 defeat by Bristol City.
"It's his thigh muscle, he felt it was tight," said manager Kenny Jackett.
"However long he is out now we have to get it right because it's been lingering for a couple of weeks.
"He pulled out of the Ireland squad and obviously it hasn't quite recovered.
"It's not badly torn or in a bad way, but we must make sure we get it right now because it can't re-occur again."
Colchester midfielder John-Joe O'Toole has undergone surgery in a bid to cure his groin injury.
O'Toole, who missed a significant part of last season after sustaining a cruciate ligament injury, has been out of action since October.
The Us had hoped that the former Republic of Ireland Under-21 international would be back in action by now but it is unlikely he will return before December.
Physio Tony Flynn told cu-fc.com: "Initially, the problem settled down with some rest but as soon as John-Joe stepped things up again, the problem flared up again.
"I expect John-Joe to be training again in seven to 10 days and he should be available to play again in two weeks time."
Brenford defender Shaleum Logan has been released from hospital following Saturday's head injury.

Barnet striker Steve Kabba could be ruled out for the rest of the season with a knee injury.
