Lions' Shane Zylstra: Signed to active roster

The Lions signed Zylstra from the practice squad to the active roster Saturday.

Zylstra was elevated from the practice squad for the maximum three times this season, and he'll continue to play in Detroit after being signed to the active roster. Zylstra will serve as the Lions' No. 3 tight end Sunday against the Texans behind Sam LaPorta and Brock Wright.
