Cowboys owner Jerry Jones says he held his breath when tight end Jason Witten took a wicked hit from Raiders linebacker Rolando McClain on Monday night.

Jones may not have exhaled yet.

Dan Patrick strongly hinted in one of the early segments of The Dan Patrick Show that Witten may have suffered a spleen injury, and that it could be serious.

A source with knowledge of the situation tells PFT that Witten indeed suffered a spleen injury, which resulted in internal bleeding. Per the source, Witten will miss the rest of the preseason.

At this time, it’s not believed that surgery will be required. But it hasn’t completely been ruled out.

Witten also hasn’t been ruled out for the Week One game against the Giants. The fact that the Cowboys and Giants open on Wednesday night could make it harder for Witten to be ready to go.
