New York (AFP) - Carolina Panthers defensive end Frank Alexander was suspended by the NFL for a minimum of one year without pay Tuesday while free agent safety LaRon Landry was issued an indefinite ban.
The Panthers announced Alexander's ban, the third on a Carolina player this week, for his third violation of the NFL's substance abuse policy.
Landry's punishment, confirmed by the NFL's website, was for his third violation of the league's performance-enhancing drug policy, according to ESPN.
Alexander, who is on injured reserve this season, was suspended twice last season for substance abuse violations.
He joins fellow Panthers Stephen Hill, a receiver also on the injured list who was hit with a one-game substance abuse policy violation, and defensive end Wes Horton, who was suspended four games for a performance-enhancing substance violation.
Horton was set to be replaced this week as Charles Johnson returned from the injured list for the Panthers, who take a 10-0 record into a Thursday matchup at Dallas.
Landry was suspended for four games last season for a performance-enhancing drugs ban and after his release by the Colts was handed a 10-game ban for another performance-enhancing substance violation. He had just completed serving that 10-game suspension when the new one came down.
Substances in all cases are not revealed as part of keeping player personal medical records private.
