The NFL is adding a combine for veteran players to go with the massive event it holds for potential draftees.

The veterans’ combine will take place March 22 at the Arizona Cardinals’ training facility in Phoenix. That is about one month after the regular combine in Indianapolis for rookies.

Matt Birk, director of football development, told the 32 teams about the new combine Thursday. It will be open to veteran free agents who will participate in position-specific drills, timing and testing.

In the past, some veteran free agents have been included in the NFL’s regional combines held for draft-eligible players. But the new format will serve to isolate and consolidate veteran free agents for a more-focused evaluation.

The league expects to invite about 100 free agents to the Arizona combine.
