From Wednesday, February 19 to Saturday, February 22, players arrive at Lucas Oil Stadium based on their positional groupings.
After check-in, the prospects are interviewed by NFL teams and are sent through medical testing.
Day 1 Arrivals: Wednesday, February 19
Offensive Linemen, Tight Ends, Specialists
Day 2 Arrivals: Thursday, February 20
Quarterbacks, Running Backs, Wide Receivers
Day 3 Arrivals: Friday, February 21
Defensive Linemen, Linebackers
Day 4 Arrivals: Saturday, February 22
(*The defensive backs arrive on Saturday, February 22 when the offensive linemen and tight ends complete their on-field workouts. Cornerbacks and safeties will be the last group to go through on-field drills and other workouts on Tuesday, February 25.)
While the public only sees the on-field workouts and drills, the interview and medical processes might be just as, if not more important to the NFL teams.
During the 15-minute interviews, scouts, coaches and general managers try their best to get to know each prospect on a personal level.
Also, medical red flags can pop up at the combine after the physicals. Last year, doctors discovered that Utah defensive tackle Star Lotulelei had a heart condition, which rendered him inactive for the combine.
