For the third time this month, the Saints have cut veteran tight end Tom Crabtree shortly before a game, the NFL transaction wire revealed Thursday night.

The Saints (3-4) promoted undrafted rookie linebacker Todd Davis from the practice squad. Davis already played in one game this year: a 24-23 defeat at Detroit on Oct. 19.

Crabtree first signed with the Saints following their Oct. 5 win at home against Tampa Bay. But he was released ahead of the Detroit game to make room for Davis.

He was then brought back after the Lions game, and Davis returned to the practice squad. But, after the Saints scratched running backs Khiry Robinson and Pierre Thomas with injuries before their win at home against Green Bay on Sunday night, New Orleans again released Crabtree to promote practice squad running back Edwin Baker.

Crabtree returned to the Saints' roster after the team suspended wide receiver Joseph Morgan due to an undisclosed reason. But, after scratching linebacker David Hawthorne with a hand injury from Thursday night's game at Carolina (3-4-1), the Saints cut Crabtree and again promoted Davis.

The tight end is subject to waivers because this season's trade deadline has expired.

Crabtree was in Green Bay from 2010 to 2012 — winning a Super Bowl there — and in Tampa Bay in 2013 before shuffling on and off the Saints' lineup.
