Poling makes Dolphins Practice Squad. Falcons and Steelers have announced their 10 man Practice Squad signings with Mangen and Sayles not included. Perhaps they will get signed to another NFL team's Practice Squad.
Falcolns picked for the practice squad TE Jaeden Graham instead of Mangen. The practice squad also includes TE Alex Gray, but he's a special case, part of some international program, and is the 11th member of the 10 man practice squad. They actually still have a space open on the practice squad, but adding yet another TE seems highly unlikely.
