The Chargers will be without starting linebacker Denzel Perryman for the remainder of the regular season.

The NFL on Monday suspended Perryman without pay for two games for repeated violations of rules designed to protect player health and safety, including an incident during Sunday’s win over the Dallas Cowboys.

In the second quarter Perryman was penalized for unnecessary roughness after delivering a blow to the helmet of Ryan Flournoy while the Cowboys receiver was on the ground following a catch. The play violated a rule prohibiting the use of any part of the helmet or face mask to initiate forcible contact to an opponent’s head or neck area.

The suspension was upheld upon on appeal, the NFL announced Tuesday.

“Denzel’s done a good job, a great job, of trying to take the helmet out of his play. And I know he’ll continue to do that,” Harbaugh told reporters Monday.

Perryman, tied for fifth on the team with 47 tackles, will be eligible to return to the active roster on Jan. 5, following the Week 17 game against the Houston Texans and Week 18 game against the Denver Broncos.
