Georgia Tech will hold its Pro Day on Friday morning at the John and Mary Brock Indoor Football Facility.

Nine former Tech players are expected to take part in drills for NFL and CFL coaches and scouts — center Freddie Burden, kicker Harrison Butker, linebacker P.J. Davis, defensive linemen Emmanuel Dieke, Patrick Gamble and Francis Kallon, linebacker Tyler Marcordes, punter Ryan Rodwell and quarterback Justin Thomas.

Dieke and Marcordes have already been on NFL rosters, but are using the workout to get before scouts again.

Of the seven who completed their eligibility last season, Butker was the only one invited to the NFL draft combine in February. Burden, Gamble and Kallon were given undrafted-free-agent grades by the website Draft Analyst . The site does not rate specialists.

The workout is closed to the public.
