Rookie cornerback Bryan McCann has five fumbles this season on returns, including four in the last four games.
He has only lost one fumble and has actually been pleasant surprise as returner with 23.6 average on seven punt returns and a 22.6 yard average on 20 kickoff returns.
But the Cowboys remain concerned about his fumbes. Interim coach Jason Garrett said ball security is something McCann must continue to work on.
