Coventry have signed Reading defender Adie Williams on a free transfer and he has secured a three-year deal.
Williams was keen to get his future sorted out
The 33-year-old's contract was set to expire in the summer and Reading agreed he could talk to other clubs.
Royals chairman John Madejski said: "I am naturally disappointed Adie has decided to leave at an exciting time for the club.
"I can understand he wanted to secure his long-term future and I wish him well at Coventry."
Reading's policy is not to make contract decisions until the new year and, after discussions with boss Steve Coppell, Williams was given permission to try and secure his future elsewhere.
Madejski added: "Adie Williams has been a terrific player for Reading for many, many years.
"He has been a commanding presence in defence and his experience played a major role as we established our position in Division One after gaining promotion in 2002.
"He was, of course, an integral part of our successful team in the mid-90s."
