Rangers have signed Nigeria centre-back Leon Balogun after the 32-year-old ended the season with Wigan Athletic.
The Germany-born defender, who has 32 caps, has signed a one-year contract.
Balogun had completed the season on a short-term contract with Wigan having spent time on loan from Brighton & Hove Albion before the Covid-19 pandemic.
Rangers manager Steven Gerrard believes the defender will "add strength and depth" after the long-term loss of Nikola Katic with a knee injury.
"His experience in the Premier League, as well as his international pedigree, strengthens our squad and will assist in the development of our young defenders," Gerrard said.
"Leon has just finished a round of competitive fixtures with Wigan so will hit the ground running. He's a positive and bright character and we are looking forward to his influence around the group."
