The San Diego Chargers reached Tuesday's 75-player roster limit deadline by waiving quarterback Zach Mettenberger.
The Chargers also placed running back Branden Oliver (Achilles) and guard Donavon Clark (knee) on injured reserve and waived/injured wide receiver Javontee Herndon, defensive tackle Zamir Carlis, offensive tackle Tyler Johnstone and running back Dreamius Smith.
NFL Media Insider Ian Rapoport reported that the Chargers were engaged in talks with Dallas prior to releasing Mettenberger. The Cowboys are expected to be without Tony Romo after the veteran quarterback re-injured his back in a preseason game versus Seattle. The Minnesota Vikings could also be in the market for a veteran quarterback with Teddy Bridgewater suffering an apparent serious knee injury Tuesday.
Mettenberger was claimed off waivers after Tennessee released him in May and was expected to challenge Kellen Clemens for the backup role. The 25-year-old Mettenberger completed just 2-of-8 passes for 22 yards and an interception in a preseason game versus the Titans.
A sixth-round selection in the 2014 draft, Mettenberg was thought to have a strong chance to make the team after playing under San Diego offensive coordinator Ken Whisenhunt during his time with the Titans.
