Newhouse, 23, went unselected in the 2005 NFL Draft after lettering four years at Northwestern (La.) State, the school that produced Packers quarterback Craig Nall. A Division I-AA All-American as a junior and three-time All-Southland Conference selection, he helped the Demons to a 2004 league championship. All told in 42 games, he posted 155 tackles (67 solo), 29 stops for loss, 7 sacks, two forced fumbles and one fumble recovery.
The 6-foot-1, 313-pound Newhouse was a SuperPrep All-America selection at Emory (Texas) Rains High School. His first name is pronounced QUIN-ten.
Samp had signed as a non-drafted free agent April 29. He injured his hamstring earlier this week in practices for rookies, but said he was ready to return for full-squad practices today.
"He's had some issues in the past with different injuries, and we just had some concerns that that may happen," said Packers coach Mike Sherman. "There was concern and we wanted to get this defensive lineman on board."
