Harrison, who originally signed with Pittsburgh as an un-drafted free agent in 2002, has played 11 of his 12 NFL seasons with Pittsburgh. The 36 year old 45 tackles and 5.5 sacks during last season's campaign.
On Saturday, Harrison posted a video to Instagram in which he enlisted the help of his children to decide which team he would join in 2015, having narrowed his choices down to Pittsburgh or Tennessee. The opinion reached in the video was split, with one advocating for the Steelers and the other pulling for the Titans.
It was speculated Harrison could choose Tennessee due to the team's hiring in February of Dick LeBeau. LeBeau was Harrison's long-time defensive coordinator in Pittsburgh. Harrison praised LeBeau in Saturday's video for helping him succeed in the NFL.
Harrison decided to retire after his 2013 season with the Cincinnati Bengals, only to 'un-retire' soon thereafter and re-join the Steelers in 2014, waiting to sign until three weeks into the 2014 NFL season.
Harrison has amassed 71.5 sacks and 501 tackles over his career.
