Star Lotulelei did his best to end any fears he isn't NFL worthy as the former Utah lineman and others were put through their paces at Utah's pro day. Lotulelei benched 38, one time shy of his personal best of 39, and looked strong in the other drills as well. Afterward Lotulelei said he has been training hard ever since a second opinion in Salt Lake City found the efficiency of his heart is improving. He was prevented from participating in drills at the NFL combine when a medical exam revealed his left ventricle was operating at just 44 percent efficiency instead of the normal range of 55 to 70 percent. He still won't be in the clear until he undergoes more medical testing on his heart at the "combine recheck," scheduled for April 5-6 in Indianapolis, but the theory at Utah is his heart was affected by a virus. "Even when I got it tested a week after it was showing improvement," he said. He weighed in at 6-4, 314 pounds, which was about 10 pounds less than his playing weight last year."Hopefully in the drills I showed them I can move well for a big guy," he said. Fellow linemen Joe Kruger, Dave Kruger, receiver DeVonte Christopher, running back John White and returner Reggie Dunn were among the participants. Out of all of them, Dunn created the most stir by running the 40 in 4.26. The 5-10, 172-pound Dunn set an NCAA record with five 100-yard kick returns in his career, including four in 2012, and finished with 1,482 career kick return yards. "I didn't get to play in any all-star games or things like that so I have been looking forward to this day," Dunn said. "I caught the ball well and didn't drop any passes and ran well in the shuttles so I hope a team likes me and picks me up." - Lya Wodraska
