Georgia Tech added two graduate transfers, safety Malik Rivera from Wofford and long snapper Zach Roberts from Lamar. Both will be eligible to play this season and have one season of eligibility remaining.

Rivera, from St. Johns, Fla., played in 28 games and started 17 in three seasons with the Terriers. Last season, he ranked third on the team in tackles, with 73, and had four pass breakups. His position coach for the past two seasons was Shiel Wood, now the safeties coach at Tech.

Rivera was a triple major at Wofford in mathematics, finance and computer science. He will pursue a master’s in quantitative and computational finance.

He could compete for a spot in the lineup, particularly with the loss of expected starter A.J. Gray because of a heart condition.

Roberts, from Magnolia, Texas, was Lamar’s first-string long snapper for the past two seasons. With Tech long snapper Casey Wilson having graduated and given up his final season of eligibility, Roberts can step in and compete for the position. Roberts will be in the master’s program for building construction and facilities management.

“Malik and Zach are great fits for Georgia Tech,” coach Paul Johnson said in a statement. “On the field, they both fulfill current needs on our football team. Off the field, they’re outstanding students and great teammates. We’re excited to have them join our football family.”
