By 4 p.m. Tuesday, rosters must be cut to a maximum of 75 players.
By 6 p.m. Saturday, they must be at the regular season limit of 53 active players.

However, whoever lines up at receiver has to have the ability to make plays on his own to make the passing game effective, and that hasn't happened with any regularity in the preseason.
Three veteran receivers acquired since late in the 2012 season already have been released. Let go were Mike Thomas, acquired in a trade with Jacksonville on Nov. 1, and offseason free agent signees Devin Thomas and Chaz Schilens.
