Buffalo Bills wide receiver Percy Harvin, bothered by hip and knee injuries since training camp, was placed on injured reserve Saturday and will miss the rest of the season.

This is the latest setback in what has been an up-and-down career for Harvin, who was selected in the first round of the 2009 draft by the Vikings. The Bills are his third team in two seasons.

Harvin had 19 receptions for 218 yards and a touchdown in five games this season.

Giants activate Pierre-Paul

Jason Pierre-Paul will make his season debut for the New York Giants on Sunday, four months after he lost an index finger in a fireworks accident.

The two-time Pro Bowl defensive end practiced this week and was added to the active roster Saturday. He played his last game for the Giants in December 2014 and had nine sacks over the last five games for a team-high 12 ½ for the season.

Pierre-Paul lost his finger, among other injuries to his right hand. Pierre-Paul was cleared to return to the field last week after rehabbing and working out near his Florida home.

New York placed linebacker Jon Beason on injured reserve because of injuries to his knee and ankle.

20-year-old from China is in the hunt

Kevin Kisner walked off the course in darkness with a one-shot lead at the HSBC Champions and a growing list of challengers in Shanghai.

That included Li Haotong of China, who had a 6-under 66 and was one shot behind with a gallery starting to believe the 20-year-old can deliver the biggest golf victory ever for the home nation. Dustin Johnson, who won the HSBC Champions in 2013, also was one shot back after a bogey-free 65.

The list also includes Masters and U.S. Open champion Jordan Spieth, who missed four putts inside 10 feet and still rattled off a 63 to pull within three shots.

Kisner made his first bogey of the week and at one point fell two shots behind. He rallied with a pair of birdies late in his round for a 70. Still to be determined was whether he had the 54-hole lead.

Russell Knox of Scotland was one shot back and chose not to finish in the dark. He was to return Sunday morning to play the par-5 18th.
