TORONTO - The Toronto Argonauts are going to have to make due without Steven Turner.

The speedy rookie, looking to crack the CFL team's roster as a kick returner, suffered a ruptured left Achilles tendon during training camp Monday. The native of Brampton, Ont., who grew up dreaming of one day playing for the Argos, is scheduled to undergo surgery Friday.

The Argos wouldn't say how long Turner will be out, but a ruptured Achilles tendon is often considered a season-ending injury.

Toronto selected Turner, who played collegiately at Bishop's University, in the fourth round -- 30th overall -- in the 2010 CFL Canadian College Draft. Turner posted a record time of 4.31 seconds in the 40-yard dash at the league's evaluation camp and also had a vertical leap of 43.5 inches.

Turner was a two-time QUFL all-star as a kick returner and scored six career touchdowns on both kickoff and punt returns.
