INDIANAPOLIS - Ohio State Buckeyes quarterback Cardale Jones pulled up with a hamstring injury during his second 40-yard dash rush at the NFL combine on Saturday, ending his on-field work.
Jones had been scheduled to throw in the second group of quarterbacks, but told the NFL Network he would not participate.
Jones, who measured in at 6-feet-5 and 253 pounds at the combine, has a quick turnaround to get healthy in time for Ohio State's pro day scheduled for March 11. It is expected to be one of the most heavily attended pro days this year considering the large contingent of Buckeye prospects in the 2016 NFL Draft.
Jones' unofficial time on his first 40-yard dash was 4.83 seconds. He is the No. 7-rated quarterback in this class by NFLDraftScout.com and projected as a fourth- to fifth-round draft pick.
The ability for Jones to throw well in front of NFL scouts is considered critical as he was benched by Ohio State coach Urban Meyer after struggling with consistency early last season.
"Jones has a live arm to generate easy velocity anywhere he wants on the field, but his hose lacks consistent direction with hot-cold accuracy downfield - more of a thrower than passer at this point in his development," said NFLDraftScout.com Senior Analyst Dane Brugler. "He doesn't play with anticipation and is still very raw reading coverages, needing extensive work under the hood before he's ready for NFL snaps. Jones is a developmental option whose final draft grade will be determined by his pre-draft process."
That pre-draft process now focuses on Jones' pro day in 13 days.
