CHARLESTON, S.C. - Charleston Southern football alum Johnny Robinson is back in the NFL as announced on Thursday as the former All-Conference defensive tackle was signed as a free agent by the Indianapolis Colts.

The 6-0, 292-pound prospect was previously signed by the Colts as an undrafted free agent back in early May, before being waived by the team later in the month.

A two-time All-Conference selection, Robinson was a key contributor to the Bucs' Big South title run in the 2016 season and their second consecutive FCS playoff berth. He is just the fifth Buccaneer in program history to be invited to an NFL camp joining former teammates Malcolm Jackson (2016) and Erik Austell (2017), as well Charles James (2013) and Maurice Price (2006).

Robinson was a dominant force in the interior of the defensive line for the Buccaneers over the last three seasons and wrapped up his playing career with 123 career tackles, as well as 9.5 sacks and 23.5 tackles for loss.

The Apopka, Fla. native's best season came in the 2017 season when he finished third in the Big South with 6.5 sacks and added 12 tackles behind the line of scrimmage.

His senior season, Robinson was second on the team with 3.0 sacks and added 8.5 tackles for loss at the point of the CSU defensive attack.

Robinson saved his best games for the biggest moments as Robinson posted nine tackles in the Bucs' Big South-clinching win over Kennesaw State in the 2016 season, and added eight tackles and three tackles for loss in 2017 against Monmouth.

He ended his CSU career as one of the top interior defensive linemen in program history finishing seventh in career sacks and 12th in career tackles for loss.

The Colts are in the midst of the NFL Preseason games and are scheduled to take on the Chicago Bears on Saturday, August 24, at 7 p.m. ET.
