New York — Clay Matthews, Julius Peppers and James Harrison will be interviewed next month by NFL officials in connection to a media report that linked them to the use of performance-enhancing drugs.

A letter from NFL executive Adolpho Birch that was obtained Friday by The Associated Press says Green Bay linebackers Matthews and Peppers and Pittsburgh linebacker Harrison will be interviewed when training camps open. The Packers begin practicing on July 26, the Steelers on July 29.

The letter also mentions defensive lineman Mike Neal, a free agent who will be interviewed. It does not mention the now-retired Peyton Manning, who also was cited in Al-Jazeera’s doping report in December.

But USA Today, citing an unnamed source, reported that an investigation into Manning’s possible involvement also is progressing.

The NFL first notified Matthews, Peppers, Harrison and Neal about its investigation into the report on Jan. 11. That investigation has proceeded, but Birch wrote that the NFL Players Association hasn’t responded to “multiple requests” to schedule the interviews, which would be conducted with a union representative present.

Al-Jazeera America reported allegations by Charlie Sly, who worked as an intern at an anti-aging clinic. But Sly later recanted his claims.

Golf Tie for Lead At Congressional

Bethesda, Md. — Jon Rahm and Billy Hurley III shared the Quicken Loans National lead, three strokes ahead of Vijay Singh going into the weekend at Congressional.

Playing together again Friday, Rahm and Hurley went shot-for-shot and to reach 11 under. Hurley, a Naval Academy graduate who lives in nearby Annapolis, shot a 6-under 65, and Rahm bogeyed the 18th hole for a 67 in his second round as a professional. The former Arizona State star from Spain led Thursday after a 64.

Rahm and Hurley will play in the final group today at Congressional, just behind Singh, who was alone at 8 under after a 66. Four-time major champion Ernie Els (69) was 7 under along with Webb Simpson (68), Bill Haas (69) and Harold Varner III (69).

At Rogers, Ark., Japan’s Ayako Uehara matched the course record with a 9-under 62 to take the first-round lead in the LPGA Tour’s NW Arkansas Championship.

At Madison, Wis., Gene Sauers rebounded from a bulging disk to share the first-round lead with Estaban Toledo in the PGA Tour Champions’ inaugural American Family Insurance Championship.

Boxing Fight Postponed

London — World heavyweight champion Tyson Fury was forced on Friday to postpone his rematch with Wladimir Klitschko after hurting his left ankle while training for the fight.

Fury, who stunned the boxing world in November by ending Klitschko’s decade-long reign as heavyweight champion, said in a video posted on his Instagram account that he sprained the ankle on a run 10 days ago. Doctors told Fury he needs to keep off the ankle for six-to-seven weeks.

The rematch was scheduled for July 9 in Manchester. Fury didn’t give a new date for the fight.

Possible men’s quarterfinal matchups: Djokovic vs. Milos Raonic, Federer vs. Kei Nishikori, Wawrinka vs. Dominic Thiem, and Murray vs. Richard Gasquet.
