Vikings’ Adrian Peterson says he will play this weekend against the Colts.

Adrian Peterson always has called himself a quick healer. Now he says he’s ready to come back from his latest knee surgery even sooner than he originally thought.

Peterson said Friday that he plans to return to the Minnesota Vikings backfield on Sunday against the Indianapolis Colts. His surprise announcement comes four days after he reiterated that he was targeting the game against Green Bay on Dec. 24 as his first game back after having surgery on a torn meniscus in his right knee.

“It really boils down to how I feel,” Peterson said. “What it really came down to me in my heart knowing, especially after these past two days, that I can go out there and be productive.”

Peterson practiced Wednesday for the first time since he was injured in Week 2 against the Packers. He practiced Thursday and Friday as well and was not listed on the team’s injury report, further evidence that he is fully healthy.

Peterson said he spoke to coach Mike Zimmer, head athletic trainer Eric Sugarman and his wife as he contemplated making the return one week sooner than he initially expected.

“We just have to make sure everything is good with the doctors and everything going forward, that’s all,” Zimmer said.

Talib avoids fine: The NFL declined to fine anybody involved in the Aqib Talib-Harry Douglas sideline skirmish last weekend.

The Denver Broncos cornerback tussled with the Tennessee Titans receiver one play after Douglas’ low block on cornerback Chris Harris Jr. that reverberated throughout the league.

The scrum happened on the Tennessee sideline but hardly anyone joined in. Talib ripped his helmet off and dared the Titans players to fight him. Finally, Titans linebacker Avery Williamson tossed Talib aside as officials tried to break it up.

After the game, Talib threatened to beat up Douglas the next time he sees him in Atlanta.
