Giants safety Will Hill is facing another suspension from the NFL for a violation of the league's drug policy, according to Mike Garafalo of FOX Sports.
Garaflo reports Hill plans to appeal the decision.
Ralph Vacchiano of the New York Daily News reports even if Hill wins an appeal, he is likely done as a Giant.
Hill already has served two previous NFL suspensions. In 2012, he was suspended four games in 2012 for a violation of the league's policy on performance-enhancing drugs after testing positive for Adderall, and he later sat out another four games last season for violating the policy on substance abuse. Hill said he tested positive for marijuana.
Another suspension under the performance-enhancing policy could bring an eight-game suspension for Hill. An additional violation of the substance abuse policy could result in a season-long ban.
