Former Oklahoma defensive end Frank Alexander, now with the Carolina Panthers, was suspended for four games Friday for violating the NFL’s substance abuse policy.
Alexander will be eligible to return Sept. 29 when the Panthers play the Ravens. He is expected to be a backup defensive end for Carolina this season.
He can participate in organized team activities, training camp and preseason games.
Alexander started three games last season and played in 12, recording 15 tackles and a sack. He also recorded a fumble.
He was a fourth-round pick in 2012 after an OU career that included 143 tackles and 20.5 sacks.
