Iowa's James Daniels doesn't participate in 40-yard dash at NFL Scouting Combine

When the offensive linemen went through the 40-yard dash at the NFL Scouting Combine on Friday morning, one of the top prospects was noticeably absent. 

Iowa offensive lineman James Daniels did not participate because of a strained hamstring he suffered two and a half weeks ago, the NFL Network reported. The Network said Daniels, a three-year Hawkeye starter, will do the other offensive linemen drills Friday.  

NFL Network analyst Mike Mayock has Daniels, a junior, listed as his third-best interior offensive lineman. Mayock raved about Daniels as he went through change of direction drills.

"He's a really good football player and one of the few Iowa players that have come out early in Kirk Ferentz's regime," Mayock said on the broadcast.
