Manziel remains a long shot to ever play in the NFL again. Whitehurst looked as bad as ever in spot duty on Sunday, and the Browns decided they would rather see what fifth-round rookie Kevin Hogan has to offer if Cody Kessler can't go against the Titans.
Neal set school records in passing yards (5,614) and touchdown passes (47) as a three-year starter at Concordia from 2012-14.
He spent last season in the German Football League, before catching the Saints' eye at Tulane's Pro Day last month.
Blackmon busted in the NFL due to repeated violations of the league's substance-abuse policy.
He has rarely been seen or heard from over the past few years. Blackmon will avoid jail time as long as he complies with the conditions set by an Oklahoma judge.
He's a camp body for when the Rams release or trade Nick Foles, who hasn't reported to the team.
A failed 2015 third-round pick out of Colorado State, Grayson never made a move to establish himself as Drew Brees' long-term backup in New Orleans.
A streaky and often erratic passer with a strong arm, Evans played in a simplistic one-read college offense that manufactured big plays off play action, and is significantly dissimilar from a pro-style attack.
Evans is also short by NFL quarterback standards and ran a 5.03 forty before the draft.
That gives the Bills a fourth quarterback behind Tyrod Taylor, E. He tried out for the Bills and Raiders last offseason but never earned a roster spot.
With Jones battling a sore shoulder, Trainor will probably get some run in Thursday's preseason finale against Detroit.
The Eagles have three more players to trim before Tuesday's deadline.
