Vikings head coach Mike Zimmer informed his players this morning that Matt Cassel will be the starting quarterback for the season opener against the Rams, according to a FOX Sports report.

Cassel had been battling first-round pick Teddy Bridgewater for the chance to start. But despite impressive preseason numbers from Bridgewater, which included four touchdown passes and no interceptions, it was clear throughout the summer that Cassel was firmly entrenched as the starter.

Cassel got the majority of the first-team reps during training camp and started every preseason game for the Vikings. He played nearly three quarters of Saturday night’s 30-12 win over the Chiefs.

Bridgewater, meanwhile, only received reps with the first-team offense in the preseason opener.

Since drafting Bridgewater in May, Zimmer and General Manager Rick Spielman have said that they do not want to rush Bridgewater onto the field before he is ready. And they re-signed Cassel before even picking a quarterback to be the bridge to whoever their next quarter of the future would be.

Zimmer is expected to formally announce his decision at a press conference later this morning.
