The exclusive rights free-agent outside linebacker from Kenya has been considered a project since he joined the Colts before the 2013 season. He spent last season on injured reserve with a biceps injury suffered in preseason.
Adongo, 25, spent 12 games on the practice squad as a rookie before being signed to the active roster and appearing in two games on special teams without a tackle.
At 6-5 and 270 pounds, the rugby star earned the opportunity because of his freakish combination of size, strength and speed displayed while with Southern Kings of Super 15 Rugby, the highest level of professional rugby in the world. He had never played football before he signed with the Colts.
Adongo will again compete to make the roster as a special-teams player. The Colts are overloaded at outside linebacker in their 3-4 base defense with Robert Mathis, Trent Cole, Erik Walden, Jonathan Newsome, Cam Johnson and Bjoern Werner.
Adongo, Johnson and running back Dan Herron received exclusive rights tenders on March 5. Johnson signed his one-year tender on March 10. Herron is also expected to sign his tender.
The Colts also made a qualifying offer to restricted free agent inside linebacker Jerrell Freeman. Another NFL team could make an offer on Freeman, but it’s unlikely because it would cost that team a second-round draft pick if the Colts chose not to match it.
