Duo in at Bolton as Pratley commits

The Trotters have also announced that midfielder Darren Pratley has signed a new three-year contract.

Madine arrives on a free transfer from Sheffield Wednesday, where his contract had expired, and put pen to paper on a two-year deal.

The 24-year-old made over 100 appearances for the Owls and also had loan spells at his former club Carlisle, Coventry and Blackpool.

Amos, 25, has agreed a four-year contract after he was released by Manchester United at the end of last season.

Meanwhile Pratley, who has made a total of 117 appearance for Wanderers since signing on a free transfer from Swansea four years ago, has committed his future to the club until 2018.
