The New Orleans Saints reversed two of the transactions they made last Saturday, re-signing veteran running back Tim Hightower and guard Mike McGlynn, while releasing receiver Seantavius Jones and fullback Toben Opurum.

The Saints also signed running back DuJuan Harris to their practice squad after trying out a total of four running backs. According to ESPN NFL Insider Field Yates, the Saints worked out running backs Harris, Mike Gillislee, Akeem Hunt and Darrin Reaves.

The Saints didn’t appear to suffer any running back injuries during Sunday’s 31-19 loss to the Arizona Cardinals. But backs Mark Ingram (45 snaps) and Khiry Robinson (27 snaps) were the only two tailbacks used in the game while C.J. Spiller was sidelined by a knee injury.

Spiller should return to action soon, though he has not yet practiced since undergoing arthroscopic surgery last month.

Jones and Opurum will likely return to the practice squad -- and possibly return to the active roster on game days if the Saints decide to rotate those last few roster spots depending on what they need on a given week. McGlynn and Hightower may have been released last week so that their salaries didn't become fully guaranteed for the entire year.

If Hightower actually plays in a game this week, it will be his first NFL action since he suffered a torn ACL in 2011. His recovery was stunted by an infection that went undiagnosed, and he finally signed with the Saints in January of this year while attempting a comeback.

Harris, 27, has played in a total 24 career games with the Jacksonville Jaguars and Green Bay Packers, with 263 career rushing yards and two touchdowns. He spent this offseason with the Minnesota Vikings.
