Former Blackpool defender has left fellow League One side Bury to join Motherwell on loan until the end of the season.
The 27-year-old centre bac, who will now link up with Blackpool defender Peter Hartley at Motherwell, signed a two-year deal with the Shakers in the summer after helping Blackpool win promotion from League Two.
Aldred, who is based in Bolton, was out of contract at Blackpool but was offered a new deal just days after their Wembley triumph.
It is understood Aldred’s preference was to stay at Bloomfield Road but the club opted against matching the wages offered by Bury.
He made 103 appearances for the Seasiders having first joined the club from Accrington Stanley in February 2015.
He suffered a tumultuous start to his time on the Fylde Coast having been sent off on his debut in the 4-4 draw against Nottingham Forest, before going on to experience successive relegations with the club.
But he finished his time on the Fylde Coast in style by captaining the Seasiders at Wembley during their 2-1 win against Exeter City.
He has made 23 appearances for Bury this season, scoring one goal, but has found himself out of the team in recent weeks after a poor run of form.
Bury currently find themselves rooted to the bottom of the League One table, 12 points off safety.
They sacked their second manager of the season in Chris Lucketti on Monday after the former Fleetwood Town assistant manager spent just two months in the hotseat.
Lucketti, 46, succeeded former Blackpool manager Lee Clark in November but failed to pick a league win.
