England fly-half Ford returns to Leicester
England fly-half George Ford has headed back to Leicester from Bath and Toby Flood, capped 60 times for England, has returned to the club where it all started for him, Newcastle.
Meanwhile, Wales and Lions full-back Liam Williams has been captured by Saracens, and talented by troubled Australian James O'Connor is about to don a Sale shirt - it's been a summer of comings and goings across the 12 clubs.
