Anthony Spencer’s “mild’’ knee injury has been diagnosed as a “bone bruise,’’ and the Pro Bowl defensive end has sat out the first two days of Dallas Cowboys training camp. If it seems like the Cowboys are being unusually cautious here, they are – and one of the reasons should be named “Kevin Ware.’’

Ware is the Louisville basketball player who sustained one of the most infamous and gruesome injuries ever captured on live television on May 31 in the NCAA Tournament when he snapped his tibia.

How in the world is this related to Spencer?

A medical source with knowledge of Spencer’s situation (but not affiliated with the Cowboys) tells 105.3 The Fan that the term “bone bruise’’ is a misnomer; it actually means a fracturing of the inner layer of bone. Among the issues: such an ailment weakens the outer layer of the bone, the hardest part, possibly making a serious fracture more likely down the line if it isn’t managed properly.

That may very well be what Spencer is suffering from now.

“It’s concerning to me,’’ Spencer said Monday. “It’s bothering me right now. I really don’t know what else to do. I’m just taking it day-by-day.”

But “day-to-day’’ might not quite be enough. If the Cowboys’ announced diagnosis is correct, at least six weeks of rest could end up being the wisest avenue for Spencer.

The tie to the Louisville basketball player?
