NFL players voted Thursday to ratify the new collective bargaining agreement thus officially ending the nearly five month lockout.
Sources close to ESPN's Adam Schefter say the 10 year CBA includes for the first time blood testing for human growth hormone (HGH) with the goal to implement the testing as early as week 1 of the 2011 season.
The exact HGH testing methods will come at future talks with the league and NFLPA. The NFL will be the first U.S. professional sport league to test for HGH.
Players who signed new contracts are now free to practice as a result of the CBA ratification.
Furthermore, commissioner Roger Goodell will retain power to hand out disciplinary actions under the personal conduct policy detailed in the new agreement.
Sources also say players are likely to appeal suspensions under the drug policy to an independent arbitrator.
