Chuck Pagano is back at work.

The Indianapolis Colts head coach returned to team headquarters Monday morning where he is expected to address players and coaches at a team meeting before answering questions from reporters.

Pagano took an indefinite leave from the team in late September after beginning treatments for leukemia. He completed the last of three rounds of chemotherapy earlier this month and his oncologist, Dr. Larry Cripe, says the illness is in complete remission. Last week, Cripe said he gave Pagano medical clearance to return to the team.

Pagano’s return comes one day after the Colts (10-5) clinched a playoff berth. They went 9-4 in his absence.

With nine wins, interim coach Bruce Arians tied the NFL record for most wins after a midseason coaching change.

Seven former players have sued the NFL in Philadelphia over the league’s handling of concussion-related injuries, the first potential class-action lawsuit of its kind. The players accuse the league of training players to lead with their heads, failing to properly treat them for concussions and trying to conceal any links between football and brain injuries. The plaintiffs include two-time Super Bowl champion Jim McMahon, who has said he played through five concussions but now frequently walks around “in a daze.”
