Zylstra (knee) is questionable for Sunday's matchup against the Rams, Eric Woodyard of ESPN.com reports.

EDGE Analysis

Zylstra logged three limited practices heading into Week 15 against the Rams, a step up from his practice progression in Week 14 when he ended the week as a non-participant. If the 29-year old does return, he would be making his first appearance since Week 2 against the Bears. The fifth-year pro plays a majority of snaps on special teams but could possibly see a larger role on offense with Sam LaPorta (back) on injured reserve.
