Tranmere Rovers have turned defender Calum MacDonald's loan deal into a permanent 18-month contract, the club has confirmed.

The exciting left back has played 24 times for Tranmere so far this season, and has completed the full 90 minutes in the club's last four league victories, including last weekend’s 1-0 victory at Morecambe.

The 23-year-old initially joined the club on loan, but has now made his stay a permanent one.

Rovers boss Keith Hill said: “It is a great approach from the Club to protect our interests going forward by turning Calum’s loan deal into a permanent one.

“I have really enjoyed working with Calum so far, and he improves our opportunities of winning football matches, so I am delighted he has committed his future with us.

“We want to improve players and he has got the appetite to improve. Calum has the desire and the determination, and he is someone we want to continue to work with.

“We are really pleased that he is committed to what we want to achieve this season and, in the future, as well.”​
