Former Millwall midfielder Martyn Woolford has signed for League One side Sheffield United on a two-year contract.
The 29-year-old was a free agent following his release by Millwall at the end of last season.
By moving to Brammall Lane, he rejoins Nigel Adkins, who he worked under at Scunthorpe United.
"We are very aware of the talents Martyn brings to Bramall Lane," Blades boss Adkins told the club website.
"He can play in several attacking positions, is fit, strong, robust, honest, hard-working and has a fantastic professional attitude. He has been consistently available for selection over many seasons and knows the demands required of this level."
Woolford, who scored three goals in 40 appearances in his final season as a Millwall player, is United's first signing of the summer.
