IRVING -- With inside linebacker Sean Lee questionable with a hamstring strain, it means Leon Williams will take over his spot on special teams. If necessary, Williams will also back up Bradie James on the strongside in the nickel package.
"That's what I'm focused on because it can change the game," Williams said of special teams.
Williams was one of the last players to make the team in a crowded field of linebackers. He has some experienced. Williams signed as an undrafted free agent with Cleveland in 2006 and after playing 46 regular season games, including 12 starts, he was released after the 2008 season.
Williams spent a year with the United Football League's New York Sentinels and former Cleveland Browns defensive coordinator Todd Grantham told the Cowboys to give Williams a look after the UFL season.
The Cowboys liked his athletic ability and decided to give him a chance.
"I felt like the training camp I had was the best of my career," he said. "I would have felt alright wit myslef if I was cut."
