The Indianapolis Colts signed center Thomas Austin, guard Marcus Hall and wide receiver Nu’Keese Richardson.
They cut offensive guard Chad Anderson, waived-injured outside linebacker Daniel Adongo and defensive tackle Jeris Pendleton and waived cornerback Brandon Burton from injured reserve with an injury settlement.
Austin has played previously for the Carolina Panthers and Houston Texans and was on the Colts' practice squad last year.
Hall was with the Colts earlier this year before being cut. He went undrafted out of Ohio State.
Richardson was signed last week before being released this week and is now back on the roster.
Anderson was signed by the Colts in July before being released. He played for the LA Kiss of the Arena Football League previously.
Adongo was signed by the Colts as a free agent last year. Last season, he saw action in two games on special teams. Prior to joining the Colts, Adongo played professional rugby.
