Cassel was signed in the offseason to back up Christian Ponder, who missed the Week 4 game against the Steelers with a fractured rib. Cassel played well against Pittsburgh and helped lead Minnesota to its first win of the season.
That led to speculation that Freeman, a 2009 first-round pick, might be on a 12-game trial in Minnesota, and Ponder's future with the team could be up in the air.
General manager Rick Spielman said earlier this week that Freeman's addition wasn't a reflection on Ponder, and coach Leslie Frazier reiterated Tuesday that when Ponder is healthy, he's the starter.
Except that, according to Schefter, the Vikings have cleared Ponder to play, and Cassel is still expected to take the field with the rest of the Vikings' offense this Sunday.
If true, Ponder's hold on the No. 1 job could be much more precarious than the team is letting on. And it's reasonable to assume that as soon as Freeman learns the playbook, the organization will want to see what he can do.
