Rams sign Robert Quinn to 4-year contract extension

The St. Louis Rams have signed defensive end Robert Quinn to a four-year contract extension, the team announced Saturday.

The deal, which keeps Quinn under contract through 2019, is worth $66.575 million and includes $41.2 million in guaranteed money, ESPN's Adam Schefter reports.

"This is an exciting day for the Rams,” head coach Jeff Fisher said in a statement. "I'm extremely happy for our organization as well as Robert and his family. 

"I would like to thank Stan Kroenke for his support in making this happen. Robert's commitment to hard work has made him one of the best defensive ends in the game, as both a pass rusher and a run defender. We're thrilled that Robert will be a part of our defense for the long term."

A 2011 first-round pick out of North Carolina, Quinn recorded two tackles in the Rams' season-opening loss to the Minnesota Vikings.
