NFL senior vice president Adolpho Birch said Thursday the league and players association need to reach agreement soon on HGH testing.

The NFL and the union agreed in principle to HGH testing when a new 10-year labor agreement was finalized in August 2011. But protocols must be approved by both sides, and the players have questioned the science in the testing procedures, delaying implementation.

"The longer we continue to stall out on this issue or we don't have an effective regimen in place, it's a disservice to all of us," Birch said at the NFL's scouting combine in Indianapolis. "We need resolution. This is enough. We've been talking about this for two years."

On Tuesday, the union said in a conference call it favors HGH testing but only with a strong appeal process.
