Linebacker Rolando McClain faces a four-game fine for violating the NFL’s substance-abuse policy, sources told ESPN.com.

McClain is a pending free agent after posting 81 tackles in 12 games for the Dallas Cowboys last season.

According to the league’s new policy, a player receives a fine for a third failed test. A fourth failed test results in a four-game suspension. McClain is appealing the fine, ESPN.com reported.

The eighth overall pick in 2010 by the Oakland Raiders, McClain retired after the 2013 season. He then changed his mind and signed with the Baltimore Ravens last offseason, but he decided to retire again.

When the Cowboys lost linebacker Sean Lee to a torn ACL in the spring, they lured McClain out of retirement, acquiring his rights from the Ravens in July. He ended up starting 12 games for the Cowboys and finishing second on the team in tackles.

—Head coach Tom Coughlin said the New York Giants want Jason Pierre-Paul to retire with the team. General manager Jerry Reese is not quite as willing to show his cards.

The Giants and the talented defensive end, eligible for unrestricted free agency March 10, are in negotiations. How advanced those talks are, Reese will not say.

“We’re talking, but that’s all I’m going to say about that,” Reese said at the 2015 NFL Scouting Combine in Indianapolis.

Reese was at the podium Saturday morning during the start of on-field quarterback workouts. He said that would not preclude the Giants from looking at a quarterback with the ninth overall pick. He described the Giants as getting healthy and moving in the right direction toward the salary cap. That might open the door to using the franchise tag if negotiations are not completed with Pierre-Paul.

“We’re going to keep our options open with respect to that,” Reese said.

—The San Diego Chargers agreed to terms on a four-year contract with tackle King Dunlap on Friday.

“I am glad to be back with the Chargers organization,” Dunlap said. “I can’t say thank you enough to Dean Spanos, as well as Tom Telesco, Coach McCoy and Coach Joe D (D’Alessandris) for helping this day to arrive. It’s an honor and a blessing and I’m ready to get back to work.”

The 6-foot-9, 330-pound Dunlap was the team’s Lineman of the Year in 2014 after starting all 16 games for the first time in his career. He was set to become an unrestricted free agent.
