They won't release Stallworth because that symbolic move would cost them about $7.6 million on their salary cap. That figure is derived from details of the seven-year, $35 million contract he signed as a free agent in 2008.
As a result of Goodell's suspension, the Browns will receive cap relief of $745,000, which is Stallworth's base salary.
The Browns won't have to formally act on Stallworth's roster status until he is reinstated by Goodell after the Super Bowl in February. By then, the NFL is expected to abolish the salary cap and Stallworth, in all likelihood, will become a former Brown.
