Sky Sports understands Millwall and Bristol City are eyeing moves for free agent Marlon Harewood.
Harewood is available on a free transfer after leaving Barnsley at the end of last season.
A number of clubs are thought to be weighing up moves for the 33-year-old, with Millwall and Bristol City leading the chase for the former Nottingham Forest and West Ham hit-man.
Millwall boss Steve Lomas has made a new striker one of his top priorities and Harewood is thought to be among his top targets having played with him during their time together at West Ham.
Bristol City chief Sean O'Driscoll is looking to build a side capable of winning promotion back to the Championship and he is in the market for striking reinforcements after seeing Jon Stead leave Ashton Gate this summer.
Hussey, who becomes Albion's fourth new arrival this summer, was released by the Dons at the end of last season.
It was the 24-year-old's second stint with the London club, having been signed from there by Coventry in 2009.
He played 65 games in the Championship and League One during a four-year spell with the Sky Blues.
Hussey's arrival signals the possibility of a new role for last season's established left-back Damien McCrory.
"I see Chris predominantly as a left-back and that may mean that I'm toying with the idea of playing Damo one further forward," said Burton boss Gary Rowett.
"But at the same time, I think Chris can play the forward role as well and, in any case, ideally, you want competition for every position.
"He is equally comfortable going forward and defending, so I think we have a really good player on our hands. He has undoubted quality and, like a lot of our others, he's at the right age to go again, I hope."
Albion are due to travel to Spain for a pre-season training camp and Rowett hopes to tie up at least two more signings before they depart on Sunday.
