Alexander was reinstated Monday following a 10-game suspension for violating the league's substance abuse policy. The Panthers have been granted a seven-day roster exemption for Alexander, meaning he doesn't currently count toward the 53-man roster. He has 37 tackles, 3.5 sacks and three fumble recoveries in his first two seasons, and if he has kept in shape during the suspension, the Panthers could certainly use help along the defensive line.
