Rotherham United have signed experienced forward Duncan Watmore and Leicester City midfielder Brandon Cover on permanent deals and completed the loan signings of Aston Villa defender Lino Sousa and Manchester United forward Gabriele Biancheri.
Former Sunderland and Middlesbrough man Watmore, 31, was a free agent after leaving Millwall at the end of 2024-25 and has signed a contract until the end of the season.
Cover, 22, made one appearance for the Foxes and has signed an 18-month deal with the Millers.
Sousa, 21, and Biancheri, 19, have not featured for their parent clubs and will spend the rest of the season with Rotherham.
All four players could make their debuts for the Millers in Saturday's home game against League One leaders Cardiff.
Matt Hamshaw's men have won their past two games to move out of the relegation zone on goal difference.
