National signing day is 19 days (and counting down...) away.

Tennessee, which has 18 commitments for the class of 2013, is hoping to sign 27 prospects on signing day. Five of those players have already enrolled early for the spring semester.

One of Tennessee's biggest priorities is holding on to the commitment of Memphis White Station defensive end Jason Carr, who committed to the Vols last January.

Could Tennessee be in trouble of losing Carr? Chad Simmons of FoxSports/Scout believes that's the case.

DE Jason Carr is on a plane headed for Tuscaloosa right now. #Alabama is school to beat imo. Still #Tennessee commit, but unlikely signee.

It's tough for any prospect - even one committed to Tennessee - to turn down an offer from Alabama.

Carr, who's Tennessee's highest-rated commitment in the 2013 class according to Rivals.com, also has opportunities with LSU, Ole Miss and Mississippi State.

With the defensive line being a big recruiting priority for Tennessee, it will be critical for the Vols to sign Carr. He has already taken an official visit to Knoxville and isn't expected back in town between now and signing day.

Where will Carr sign? We'll have to wait and see.

In the meantime, we can discuss. And we will do so Saturday morning on Football Futures - presented by Tropical Smoothie Cafe. Be sure to listen at 10 a.m. eastern time as we discuss the latest in recruiting.
