FLORHAM PARK, N.J. (AP) The New York Jets have signed rookie tight end Matt LaCosse, and waived-injured rookie defensive lineman Davon Walls.

The 6-foot-6, 240-pound LaCosse was signed by the Giants as an undrafted free agent on May 7 and waived Aug. 1. He adds depth to what has become a crowded tight ends spot, joining Jeff Cumberland, Jace Amaro, Kellen Davis, Steve Maneri, Wes Saxton and Arthur Lynch. Amaro has a sprained shoulder and will not play against the Giants on Saturday night.

LaCosse had 38 catches for 397 yards and six touchdowns in four seasons for Illinois.
