If he is to be believed, linebacker Stephen Tulloch's tenure with the Detroit Lions is coming to an end.

"What a journey it's been Detroit! Five years of some of the greatest memories of my career," Tulloch said on an Instagram post Thursday.

"Such as life there is constant change. But change that I'm looking forward to. As one chapter closes in my career another one opens up."

That next chapter could come in Philadelphia, where the 31-year-old would reunite with Eagles defensive coordinator Jim Schwartz.

Tulloch, who finished 2015 with 107 tackles, one sack, one forced fumble and two fumble recoveries, would be joining a crowded linebacker corps with the Eagles, if Philadelphia is in fact his next destination.

Finding a home for the 10-year veteran with the Eagles would be a challenge, especially in the starting lineup. Second-year standout Jordan Hicks should be entrenched as the starting middle linebacker and Schwartz has spoken glowingly of Mychal Kendricks. Then there's the curious case of Kiko Alonso who was injured during the one-year he crossed paths with Schwartz with the Buffalo Bills.

Should the Eagles move on from DeMeco Ryans in a salary cap slashing move, Tulloch would make sense as a veteran to rotate inside with Hicks who already has both knowledge and experience in Schwartz' attacking scheme.

Last season was the first that Tulloch was not consistently a three-down player since signing with the Lions in 2011, which could leave him more open to the idea of taking on a rotation role with the Eagles.

In addition to Tulloch's familiarity with Schwartz, he began his career playing linebacker behind Jim Washburn's wide-nine front with the Tennessee Titans, something none of the current linebackers on the roster have been asked to do.

The biggest question mark facing a potential Schwartz-Tulloch reunion seems to be whether or not the Eagles can land him on a deal cheaper than Ryans' $3.5 million cap hit and if he would be willing to take on a part-time role.

If both bridges can be crossed, Tulloch could be an ideal insurance policy for Hicks and veteran voice in meeting rooms to maximize the new scheme Schwartz is about to implement this season.

However, should Tulloch and his representatives still believe he can be a starting player in this league, it is unlikely that he joins a crowded group that includes Hicks, Kendricks, Alonso, Najee Goode, Marcus Smith and for the moment Ryans.

The fact that Connor Barwin will move to left defensive end this season creates a potential opening at linebacker, depending on where Schwartz views each player's best position to contribute.

Plenty can happen between now and free agency opening on March 9, but Tulloch's name should be one to keep an eye on. Especially if Ryans is let go.
