Former USC and current Tennessee Titans running back Stafon Johnson on September 28, Johnson was lifting weights at the USC facility, and a barbell with 275 pounds stacked on it slipped. The bar came down and crushed his larynx, and Johnson had to undergo emergency surgery. He had a breathing tube through most of October, and doctors told him that he could have died had his neck muscles not been so well-developed. Few expected Johnson to make a comeback that included the NFL, but Johnson started working with Gaines, got his strength back, and got on with the Titans as an undrafted free agent. Johnson was making tracks in his first preseason game on Saturday night against the Seattle Seahawks, gaining 23 yards on three carries, until his right leg was trapped underneath him on a swing pass at the end of the third quarter. Johnson went down and stayed down as the cart came out to take him off the field. Johnson's right leg was placed in an air cast, and Seahawks coach Pete Carroll (who coached Johnson at USC) came out to talk to the young man. The entire Titans team came out on the field to pray as Johnson was loaded onto the cart. Everyone knew what was at stake, and what Johnson had gone through to get there. Initial reports indicate that Johnson may have a dislocated ankle, which would likely mean the end of his 2010 season. Whatever the final diagnosis may be, it was a heart-wrenching moment for those who have been so impressed with the strength and courage Johnson has displayed during his amazing comeback
