I knew our first season of ownership would include challenges along the way, and we will not shy away from hard work, nor will we be deterred by adversity,” Harris said in the statement.

“As Coach [Ron] Rivera and I discussed, all of our energy for the remainder of the season will be focused on playing better, more consistent football and developing our players while intently evaluating the areas in which we need to improve this offseason.

“Our fans deserve a team that can compete with the NFL's best and win sustainably over the long-term. I will not waver from that mission. Thank you to our fans for the ways in which you've breathed new life into our franchise. We have not been good enough this season, but our resolve for the future is unbroken.”
