Kevin Shaffer became the second Browns veteran released in a span of 24 hours as the team parted ways with the right tackle Thursday.
Receiver Joe Jurevicius had his contract terminated Wednesday by new coach Eric Mangini and general manager George Kokinis.
Shaffer is reportedly due a $1 million roster bonus Friday and the two sides could not come to an agreement on a restructed deal. Shaffer's agent Alan Herman said in an email that the lines of communication are still open and that ''the next 24 hours are crucial concerning Cleveland.'' Herman said Shaffer would also explore free agency.
A seven-year veteran who spent three seasons with the Browns, Shaffer was due to make $2.65 million in 2009. In March, 2006, he was signed to a seven-year, $36 million contract with at least $10 million guaranteed.
Shaffer was brought in by former general manager Phil Savage to play left tackle. In 2007, he was supplanted by third overall pick Joe Thomas, shifting Shaffer to the right side.
Shaffer looked to have a shaky hold on that spot last season until Ryan Tucker underwent right knee surgery and was placed on injured reserve on Nov. 1. But Savage continued to praise Shaffer's reliability. Shaffer missed only one start in three seasons, that with a concussion in 2008.
The Browns also announced the signing of linebacker David Bowens, a 10-year veteran who spent the last two seasons with the New York Jets. Bowens received a four-year, $7.2 million contract.
''David is another example of the emphasis that we place on toughness, leadership and versatility,'' Kokinis said in a statement. ''He has played inside and outside linebacker and has been a core special teams player throughout his career.''
