With injuries mounting, Rader's addition could provide much-needed depth at the tight end position. With David Thomas sidelined for the year, and Marcellus Rivers no longer on the roster, the Patriots need another tight end to backup Ben Watson and Kyle Brady.
Rader was originally signed by New England on September 3, 2007 and placed on the team's practice squad. He was hurt and eventually released on September 30th. Although Rader saw no action with New England, he will likely provide some relief for Brady who has fought injury concerns issues throughout camp and the early part of the season.
