A couple of late additions to the roster have been confirmed. I believe there will be a handful more announced, as well. But so far, here are the confirmed guys who have made the team and are officially on the roster so far. I'll update this list as it becomes official.
No. 15 Mikal Hall (QB - Aliquippa) - Freshman is now officially now listed on the roster. Wasn't throughout camp despite working as the fourth quarterback. Initially tried to make it as a receiver but was moved to QB when Michael DeBaugh left.
No. 92 Tyler Potts (DE - Hopewell/Geneva College) - A late transfer, Potts hasn't practiced yet with the team and I believe he'll have to sit out this year since he moved up a level. Potts should be a junior when he does begin playing. He's an excellent story, too, as he battled leukemia his senior year of high school. Potts made it back onto the field last year at Geneva.
No. 41 Luke Zearing (FB - Cambria Heights) - Zearing was a late commit this past spring and is now officially on the roster after participating in camp.
No. 49 Luke Mueller (LB - Seneca Valley) - Mueller was a transfer from Thiel College. He's listed as a freshman but I believe that will eventually be changed. He's impressed in camp and was working with the third team at middle linebacker.
No. 17 Luke Centofanti (WR - West Mifflin) - Younger brother of junior linebacker Mark, the younger Centofanti definitely impressed in camp with his hands and route running. He'll be on the scout team but he definitely stuck out as a walk-on.
No. 89 D.J. Hayes (WR - West Mifflin) - High school teammate of Centofanti's, Hayes has more speed and also impressed at times with his hands. He'll also be on the scout team.
Also two number changes. Freshman DB Brian Jones will switch from No. 15 to No. 30, which indicates he'll likely be active. Same with freshman QB Derik Abbott, who goes from No. 10 - shared with LB Adrian Perez - to No. 19.
