Matt Carroll is re-signed by Carlton after a successful trial period during the pre-season supplemental selection period (SSP).
"He had a tough year last year, hampered by injury, but has shown a great level of determination and maturity in the way he has gone about his rehab program," Blues list boss Nick Austin said.
"Having been here all last year, Matt has already grown a great connection with the coaches and players: he has continued to train with us over the pre-season and has impressed since day one."
