With the start of the NFL Scouting Combine on Tuesday, prospects will have another opportunity to break running back Chris Johnson's 40-yard-dash record of 4.24 seconds.
Tuesday on SiriusXM NFL Radio (via ESPN.com), Johnson spoke about the record and the possibility of it falling this year.
"I didn't think it would hold on this long," Johnson said. "To be honest, I don't want to see the record go. But if somebody does break it...I'll be happy for them and give them a handshake and congratulate them."
Johnson set the record in 2008 as a prospect coming out of East Carolina, which helped him get drafted 24th overall by the Tennessee Titans.
