Cardiff Blues have signed former Dragons and Ospreys centre Tom Isaacs from Gloucester until at least 2016.
Cardiff-born Isaacs joined Gloucester in March but failed to establish himself at Kingsholm.
The 27-year-old was restricted to three replacement appearances in the Premiership and two starts in the LV= Cup.
"I want to be playing regular rugby and couldn't turn down the chance to return to my home city," he said.
"Gloucester is a great traditional rugby club but, with a change in rugby management after my signing, opportunities have been limited this season."
Isaacs is a former Wales Under-20 international and was a member of the Wales side which won the Sevens World Cup in 2009.
Cardiff Blues director of rugby Mark Hammett said the arrival of Isaacs strengthened a squad which had been affected by injuries and international call-ups.
"He is a strong ball carrying centre who can make things happen and I've been impressed by his tremendous attitude towards both training and games," Hammett said.
"We're excited to welcome him back to his home city and look forward to seeing him in action for Cardiff Blues."
Isaacs has also played for Bridgend Ravens, Cardiff, Glamorgan, Neath and Swansea as well as spells with Newport Gwent Dragons and Ospreys.
