The 2012 NFL Combine in Indianapolis, Ind., begins on Wednesday, Feb. 22, with the arrival of offensive linemen, tight ends and special teams players. The rest of the position players will arrive on a staggered schedule: the offensive skill players start on Thursday; the defensive linemen and the linebackers get underway on Friday; and the defensive backs mark the beginning of the end on Saturday.

As a result of this tiered system, players that begin on Wednesday will finish on Saturday. And those who start on Saturday will finish on Tuesday, Feb. 28.
