The Lions continued what could be a busy day, adding some defensive line help.
According to Adam Caplan of TheSidelineView.com, the Lions signed defensive lineman Jason Jones, formerly of the Seahawks.
Jones played well under Lions assistant Jim Washburn when both were in Tennessee, and this offers some cover for their anticipated loss of Sammie Lee Hill to the Titans.
The Lions have already brought back cornerback Chris Houston, and are in the process of courting running back Reggie Bush.
