The Pittsburgh Steelers re-signed outside linebacker James Harrison to a two-year contract Sunday.

Financial terms of the contract were not disclosed.

Harrison, who turns 37 in May, will enter his 13th season in the NFL in 2015 and 12th in Pittsburgh.

In 2014, Harrison contributed 45 tackles and 5.5 sacks in 11 regular-season games (four starts) with the Steelers, and had two tackles in the team’s postseason contest.

Harrison originally signed with the Steelers as an undrafted free agent in 2002. He has appeared in 157 regular season games (108 starts).

Harrison earned five consecutive Pro Bowl selections from 2007-11 while helping lead the Steelers to two Super Bowl championships (XL and XLIII) in three title game appearances.

Harrison ranks tied for first in team history with 17 multi-sack games and is second with 69.5 sacks. He also had two sacks in his one season with the Cincinnati Bengals in 2013.

On Saturday, Harrison announced on Instagram that he would soon choose between re-signing with the Steelers and joining his former defensive coach, Dick LeBeau, with the Tennessee Titans.

Harrison posted a video on Instagram that featured his two young sons. One son says he should return to the Steelers and the other one says he should sign with the Titans.

“The opinions of my support team are split, but for me, my love for the man who both started, and made my career what it is, is undeniable,” Harrison wrote on Instagram. “There are no words that I can find that would do justice for everything Dick LeBeau has done for me & my career and nothing can compare to that!

“I also have a great amount of love for Steelers Nation & the Steelers organization. I’m going to pray on this and let God guide me in the right direction.”

LeBeau parted ways with the Steelers in January after 11 seasons as the team’s defensive coordinator. Harrison played 11 of his 12 seasons for LeBeau in Pittsburgh. LeBeau joined head coach Ken Whisenhunt’s staff with the Titans in February as an assistant head coach/defense.
