Here is all the latest transfer news and speculation from around the SPFL:

Dons sign keeper

Joe Lewis has been told to fight for his place at Aberdeen after the club signed a new goalkeeper. The Dons have added Kelle Roos from Derby County on a two-year deal. Jim Goodwin said: “Joe Lewis is a fantastic goalkeeper and has been a great servant to Aberdeen. He’s got two years left on his contract but I want someone in there alongside Joe, both competing for that No 1 spot. Kelle brings with him a wealth of experience and he will help to enhance the goalkeeping team we have at the club.” (The Scotsman)

Griffiths future

Leigh Griffiths is searching for his new club as he looks to get back to his fighting weight. The striker has been working with a boxing trainer to get him to 73kg. He hopes getting in shape will help him find a new club. He said: “I’m not going to lie, it gets lonely. It knocks my confidence not having my future sorted but people such as Martin Clifford at the boxing gym have been brilliant at keeping my head above water. Six days a week I’m in training and all of this work will come to the fore when I get back onto the pitch." (Sunday Mail)
