Kansas City Chiefs cornerback Dunta Robinson will sit out Sunday's game against the Dallas Cowboys.
Robinson missed practice all week after Chiefs coach Andy Reid excused him to attend to an undisclosed family matter.
According to a source, Robinson rushed home to be with a first cousin, who has lapsed into a coma and requires the assistance of a breathing machine after being struck by a vehicle.
Robinson signed with the Chiefs as a free agent after starting for the Atlanta Falcons and Houston Texans in previous seasons. He is the third cornerback for the Chiefs, meaning he would have been involved in a vital matchup in Kansas City's defensive game plan.
When the opponent deploys three wide receivers, Robinson covers the slot receiver, which means he likely would have lined up against Dallas' Miles Austin.
In 2009, Austin made the first start of his NFL career against the Chiefs at Arrowhead, replacing injured Roy Williams. Austin caught 10 passes for 250 yards and two touchdowns, including the game-winner in overtime.
