The New Orleans Saints signed tight end/long snapper Garrett Griffin Monday and waived defensive end Mitchell Loewen.

Loewen, an undrafted free agent signed in May, played both defensive end and tight end at Arkansas but was listed as a defensive end with the Saints.

Vincent Brown is dean of New Orleans Saints WRs -- and he's only 27 The next-oldest receiver is Reggie Bell, who just turned 24. Like most of the receivers on the roster, Bell has yet to play in the NFL game.

He was seen last month at a charity softball game wearing a walking boot on his foot and didn't participate in any of the organized team activities open to the media. The Saints waived Loewen with a non-football injury designation.

Griffin was offered a contract after trying out during the team's rookie minicamp. He graduated from the Air Force Academy last week and has a two-year military service obligation pending.

It's unclear if the Saints view Griffin primarily as a tight end or long snapper. The Saints incumbent long snapper is Justin Drescher. Chris Highland, signed earlier in the spring, was waived after rookie minicamp.

The Saints have six tight ends on the roster in addition to Griffin. They are: Coby Fleener, Mike Hoomanawanui, Josh Hill, RaShaun Allen, Chris Manhertz and Jack Tabb.
