(Reuters) - The Dallas Cowboys signed veteran running back Sammy Morris after putting rookie DeMarco Murray on the season-ending injured reserve list with an ankle injury, the team said on Tuesday.
The 34-year-old Morris, one of the final players cut by the New England Patriots ahead of the 2011 National Football League (NFL) regular season, will backup Felix Jones, who will take over the starting role from Murray.
Morris, an 11-year NFL veteran who has played for Buffalo, Miami and New England, has rushed for a career total of 2,995 yards and 26 touchdowns.
He has a long association with Cowboys coach Jason Garrett. The two were team mates with Miami in 2004, and Morris played under Garrett when he was an assistant coach for Miami in 2005 and 2006.
Murray, the team's leading rusher, was ruled out for the season after suffering a fractured right ankle and high ankle sprain in Sunday's loss to the New York Giants.
