The New Orleans Saints placed fullback Austin Johnson on injured reserve Tuesday, ending his season. He was dealing with a knee injury that he sustained against the Green Bay Packers two weeks ago.

The Saints also signed tackle Nick Becton off the Giants' practice squad and added running back Tauren Poole to the practice squad. Poole was most recently with the Carolina Panthers.

With Khiry Robinson and Pierre Thomas both injured, Edwin Baker, who was promoted from the practice squad, remains on the active roster.

Johnson, a 2013 undrafted rookie free agent, was having a breakout season after spending last year on the practice squad. With Erik Lorig sidelined for the first few weeks, Johnson played in seven games, with one start. He had eight rushing attempts for 22 yards, along with a receiving touchdown.

Tackle Zach Strief was injured last Thursday against the Carolina Panthers after taking a knee to the back following a play. Strief said in the locker room after the game that he was "bruised up," but there's been no updates on his status since because the Saints have not practiced yet.

Becton was a 2013 undrafted rookie out of Virginia Tech. He spent half of the 2013 season on the Chargers active roster, and the latter half on the practice squad after appearing in one game. He played both left and right tackle for the Chargers.

He waived in August and added to the Giants practice squad in September.

The signing of fullback Michael Zordich was also made official on Tuesday.

Zordich was one of seven players brought in for a tryout on Monday.

Former Saints defensive back Rod Sweeting was added to the Bills practice squad on Tuesday, while George Uko, who spent time with the Saints during the preseason, was released from the Bucs' practice squad.
