Claiborne had been dealing with a hamstring injury but had to curtail some of his rehab work because of the family issue. The Cowboys weren't expecting Claiborne to play against the Chicago Bears on Monday night because he still wasn't physically ready to play.
"He's very close with his family," Cowboys owner/general manager Jerry Jones said on 105.3 The Fan on Tuesday morning. "Very close in Louisiana and suddenly his father passed away at a relatively young age. He was not what I wold call an older man. Having said that, it tore his world up so he immediately left to be with his family. We knew he wasn't going to play this week and that's besides the point. He wanted to be with his family and we're giving him all of the time that he needs there or wants."
On Dec. 8, Claiborne tweeted: "Man God be working. Took my daddy on Wednesday (Dec. 4) and gave me a beautiful little girl on Monday."
It's the second time this season a member of the defense lost a parent. Rookie safety J.J. Wilcox's mother passed away during training camp.
