At least two veterans present for the New Orleans Saints rookie minicamp on a tryout basis are on track to sign a contract.

The Saints are expected on Monday to sign offensive lineman Khalif Barnes and tight end Clay Harbor, according to a source familiar with the situation.

For the 6-foot-6 Barnes, the return marks his fifth time with the Saints since late August 2016. He bounced on and off the active roster until November without appearing in a game, and he returned for the rookie minicamp committed by losing more than 40 pounds.

Barnes, who joined the Saints last summer weighing 358 pounds, said Saturday he is now down to 314 pounds.

Barnes entered the league in in 2005 out of Washington as a second-round pick of the Jacksonville Jaguars. He spent four seasons with the Jaguars (2005-08), before playing seven seasons with the Oakland Raiders (2009-15).

On his 11-year career, the 35-year-old Barnes has appeared in 151 games with 117 starts and can play tackle or guard.

The 6-foot-3, 240-pound Harbor turns 29 in July and entered the league in 2010 out of Missouri State as a fourth-round pick of the Philadelphia Eagles.
