The Panthers agreed to terms with Horsted on Monday, David Newton of ESPN.com reports.
Horsted is joining a Panthers tight end room that's currently depleted, as both Ian Thomas (calf) and Tommy Tremble (hamstring) are dealing with injuries. Horsted, a Princeton product, is likely an extra camp body to take some load off the recovering Thomas and Tremble, but if he impresses throughout the preseason, he could earn a depth spot on Carolina's 53-man roster.
