Tackle Alex Barron, a first-round pick of the Rams in 2005, signed as a free agent with the Saints. After a knee injury suffered early in camp, Barron has been placed on injured reserve.
The Saints announced the move on Thursday night.
Barron was traded to the Cowboys last year. He started only one game in 2010.
The Saints filled Barron’s roster spot with cornerback Quincy Butler.
