This opens a three-week window of time for the Saints to activate Hansen from injured reserve and add him to their 53-man roster.
Crawley, 27, wound up signing a three-year, $1.62 million contract with the Saints as an undrafted free agent out of Colorado in 2016. He managed to make the 53-man roster coming out of the preseason and returned to New Orleans on an exclusive rights contract.
Crawley was waived by the Saints a few months ago and later claimed by the Dolphins. Miami waived him with an injury designation last year and he was later waived from injured reserve.
Crawley signed a futures contract with the Raiders this past January before releasing him back in August. From there, he had a brief stint with the Cardinals before returning to the Saints last month.
