INDIANAPOLIS -- NFL prospect Justin Blackmon said Friday that he plans to "do it all" at this month's NFL Scouting Combine, including the 40-yard dash.
Blackmon predicted he would finish the 40 in 4.4 to 4.5 seconds.
The former Oklahoma State star is one of the top wide receivers expected to be picked in April's NFL draft.
Blackmon caught 122 passes for 1,522 and 18 touchdowns this past season.
