The New York Giants completed their initial 16-player practice squad on Tuesday by announcing the signings of four players who spent training camp with other organizations.
The players signed were running back Taiwan Jones, offensive lineman Jalen Mayfield, wide receiver Dennis Houston and tight end Tyree Jackson.
Jones, 35, is in his 13th NFL season. A 2011 fourth-round pick by the then-Oakland Raiders, he has spent six seasons with the Raiders, five with the Buffalo Bills and one with the Houston Texans.
Jones has only 53 carries for 223 yards, and 19 receptions for 260 yards over his career.
