Report: Lions won't activate Ertz off practice squad vs. 49ers

The Detroit Lions aren't activating tight end Zach Ertz off the practice squad for the NFC Championship Game against the San Francisco 49ers, sources told Jeremy Fowler of ESPN.

Ertz worked hard this week to prepare for the contest, but the team will leave him on the practice squad for this week, Fowler adds.

Detroit signed Ertz earlier in the week after backup tight end Brock Wright suffered a season-ending forearm injury in the divisional round against the Tampa Bay Buccaneers. Sam LaPorta has also been dealing with a knee ailment, but he's off the injury report ahead of Sunday's contest.

The Arizona Cardinals granted Ertz's release request in November. The 33-year-old has 27 catches for 187 yards and a touchdown in seven games this season.
