Shaka Hislop's career looks to be over after FC Dallas granted the goalkeeper early retirement because of a persistent back problem.
The 38-year-old Trinidad & Tobago international goalkeeper has been out of action for more than a month with back spasms and there are real concerns the problem will be ongoing for the rest of the season.
"He is close to recovering, but in talking with him, our trainers and a couple of doctors, we think it could be an ongoing problem."
The player signed a guaranteed contract when he joined FC Dallas from West Ham last year, and was due to earn around £110,000 this year - the second highest-paid player on the Dallas roster.
Hislop began his professional career with Reading and also played for Newcastle before joining West Ham in 1998.
He has collected 26 caps for Trinidad and Tobago, and played at last summer's World Cup.
Morrow added: "He has been a great goalkeeper, playing in England for many years, and had a great career.
"He probably didn't finish here the way he wanted to."
