Johnny Culbreath is the Lions' latest purge

Four Detroit Lions players encountered legal problems this offseason. Two have now been jettisoned from the roster.

The Lions released offensive lineman Johnny Culbreath on Tuesday, replacing him on the roster with veteran lineman Jonathan Scott. A story on the team's web site gave no specific explanation for the move or its timing, but it must be pointed out that Culbreath was charged in January for marijuana possession while in South Carolina and ultimately paid a $412 fine.

It was the first of seven incidents Lions players were involved in over the ensuing six months. Running back Mikel Leshoure and defensive lineman Nick Fairley remain with the team, while cornerback Aaron Berry was released Monday.

Culbreath was a seventh-round draft pick in 2011 and spent the year on injured reserve, so it's possible he no longer fit into the Lions' plans on the field. If the Lions thought his offense merited internal discipline, they probably wouldn't have waited six months to do it. Regardless, what's done is done. The Johnny Culbreath era is over.
