Curious case of Keenan Mace

ARLINGTON, Texas -- For a couple days at the start of training camp, Keenan Mace was a Cowboy. Today, the defensive tackle might get selected in the supplemental draft by any of 32 NFL teams.

Mace was signed as an undrafted free agent from Lindenwood University, but the NFL disapproved the contract because it said he still had collegiate eligibility, even after he played this spring for the Allen Wranglers of the Indoor Football League. He never petitioned the league to enter the draft early, which meant he had to go through the supplemental draft.

Mace, 6-4, 313, played two seasons at Lindenwood (2007, ’10), sitting out the 2008-09 seasons. He had 24 tackles and a sack in 11 games last season at Lindenwood.

Because the Cowboys are so far down the road in training camp and implementing the defense, it is unlikely they would use a pick on Mace or any of the available players in the supplemental draft. They used a seventh-round selection on nose tackle Josh Brent last year.
