WASHINGTON (AP) — Accusing the NFL players’ union of “trying to back out” of an August 2011 agreement to start checking for human growth hormone, a congressman worried aloud Wednesday that the league will head into next season without a test for the banned drug.

“Hopefully as we move down the line, players will see how incredibly ridiculous it looks for them not to ... straighten this thing out,” said Rep. Elijah Cummings of Maryland, the House Oversight and Government Reform Committee’s ranking Democrat. “We’re now getting ready to go into a third season, and it does not look very good.”

The panel held a hearing to examine the science behind the testing, and heard from experts that it is reliable.
