Utah's Star Lotulelei is the top-rated defensive tackle on NFLDraftScout.com's big board. But on Sunday we found out Lotulelei is dealing with a heart condition that could seriously hurt his draft stock and, more important, be an issue for his personal health.

CBS Sports NFL Insider Jason La Canfora confirmed with Lotulelei's agent Bruce Tollner that the defensive tackle is dealing with a heart condition that resulted in him not working out at the 2013 NFL Scouting Combine. La Canfora reports that the combine asked him not to work out until meeting with a specialist later in the week.

Chris Mortensen of ESPN reported that Lotulelei is dealing with a left ventricle that is pumping at 44 percent efficiency (verus a "normal range" of 55 to 70 percent).

The news came out after Sunday afternoon's media session with players ended. Lotulelei never spoke to the press, and his absence was certainly curious considering his position on big boards and in mock drafts.

Lotulelei is expected to undergo further tests in Salt Lake City. Tollner tells La Canfora that Lotulelei will still interview with teams in Indy and will compete in all the physical tests at his pro day in March.
