James Harrison's short Patriots career -- two regular-season games, three postseason games -- came to an end today, when the soon-to-be 40-year-old linebacker announced his retirement on Instagram:

From Pro Football Talk:

Harrison initially signed with the Steelers as an undrafted rookie in 2002, briefly spent time with the Ravens and NFL Europe's Rhein Fire, and then really made his mark with the Steelers starting in 2004. He was a Pro Bowler for five straight years from 2007 to 2011 and the NFL defensive player of the year in 2008. After one year with the Bengals in 2013, he went back to the Steelers in 2014. They cut him last season and he finished his career with the Patriots.
