Former Georgia Tech safety Corey Griffin has agreed to an undrafted free agent contract with the San Francisco 49ers. The deal was made Saturday after Griffin was not selected in this weekend’s draft.

Making the team won’t be easy. The 49ers took two safeties in the draft, Tarvarius Moore from Southern Miss in the third round and Marcell Harris from Florida in the sixth round.

Griffin has overcome long odds previously. He was a late addition to Tech’s 2013 signing class out of Sandy Creek High – he was committed to UAB – and went on to start 25 games for the Yellow Jackets.
