MINNEAPOLIS -- The Minnesota Vikings continued to tweak their roster on Sunday, reuniting offensive coordinator Norv Turner with two names from his past -- including one that should be familiar to football fans in Minnesota.

Former University of Minnesota quarterback MarQueis Gray, who played tight end for the Cleveland Browns last year while Turner was the offensive coordinator and was released by the team on Saturday, tweeted on Sunday he's joined the Vikings, who claimed him off waivers. The team also claimed former Chargers tackle Mike Harris off waivers, according to two league sources.

The moves address a pair of needs that stood out when the Vikings finalized their 53-man roster on Saturday; they only carried two tight ends, and while rookie lineman Austin Wentworth showed some potential as a swing tackle, it seemed the Vikings might look for a veteran there, like they did when they signed J'Marcus Webb at this time last year. They released Wentworth on Sunday, according to a league source, and had scheduled Harris a flight to the Twin Cities on Sunday for a physical.

The tackle missed all of last season with a broken ankle and broke his foot after returning from his ankle injury, meaning he didn't get a chance to prove himself during Chargers camp. He's fully recovered from his injuries, though, and his history with Turner made him a logical pickup for the Vikings.

According to league sources, the Vikings added tight end Chase Ford, wide receiver Kain Colter and running back Joe Banyard to their practice squad on Sunday, and planned to put Wentworth there, too, if he cleared waivers. The team also signed offensive tackle Mike Remmers to its practice squad, according to a tweet from Remmers’ agent, Brett Tessler.
