From scout.com:
The Dallas Cowboys signed wide receivers Tom Crowder, J.R. Tolver and Jamaica Rector, guards Shannon Snell and Matthew Tarullo and running back Keylon Kincade for 2006.
The six players, who were all on the practice squad at the end of the regular season, are now on the active roster.
Dallas also has rookie DE Vontrell Jamison, who was added to the active roster before Sunday's game against St. Louis.
Also, DeMarcus Ware came in fourth in the NFL Defensive Rookie of the Year contest, behind Shawne Merriman (the winner), Lofa Tatupu, and Odell Thurman.
