Former NFL quarterback Vince Young's tenure in the Canadian Football League has been derailed by a torn hamstring.
Young was released by the Saskatchewan Roughriders, his agent, Leigh Steinberg, announced Saturday via Twitter.
The injury was sustained by Young during a practice session and the team said earlier this week that he was expected to miss four to six weeks.
However, Steinberg tweeted Saturday that the hamstring was torn and his client was waived because of the time it will take to heal.
The 34-year-old Young signed a two-year, non-guaranteed contact with the Roughriders three months ago. He was expected to compete for a backup job behind starting quarterback Kevin Glenn.
The last time Young played in a game was during the 2013 NFL preseason with the Green Bay Packers, who released him before the regular season started. Young's last regular-season game was in 2011 for the Philadelphia Eagles. He retired from the NFL after the Cleveland Browns released him in 2014.
Young was the No. 3 overall pick by the Tennessee Titans in the 2006 NFL Draft. He played in the Pro Bowl in 2006 and 2009.
At Texas, Young led the Longhorns to the national championship, scoring the winning touchdown in the final seconds of a 41-38 win over USC on Jan. 4, 2006.
