Tom Crabtree’s yo-yo life with the New Orleans Saints continued Thursday as the team waived the tight end and promoted linebacker Todd Davis from the practice squad.

Crabtree has been signed and released three times in the past three weeks. He had just been added again Tuesday when the team placed wide receiver Joe Morgan on the suspended list.

But with linebacker David Hawthorne out for the Saints’ game against Carolina on Thursday, the Saints apparently decided they needed Davis.

The undrafted rookie was active two weeks ago, being added for special teams help against the Detroit Lions as the team released Crabtree. Davis had gone back to the practice after that game, with Crabtree coming back.
