Expecting to upgrade at the position, the Houston Texans have released free safety Matt Stevens, a move that will save the team about $2.5 million in cap space. This marks the second time in two years that the Texans released Stevens but, unlike in 2003, the much-traveled eight-year veteran will not be returning to the team. Stevens, 30, is now a free agent and can negotiate with other teams. In stints with Buffalo (1996), Philadelphia (1997-98), Washington (1998-2000), New England (2000-2001) and Houston, he started in 42 of 104 appearances. Stevens has 276 tackles, 13 interceptions and 31 passes defensed for his career.
