ENGLEWOOD, Colo. -- Denver Broncos coach Gary Kubiak stepped down from his dream job on Monday because of health concerns, saying "the demands of the job are no longer a good fit for me."
Kubiak missed a week of work in October after suffering a complex migraine, his second health scare in three years.

Kubiak went 24-11, including a victory in Super Bowl 50, but a 9-7 finish this season kept the Broncos out of the playoffs.
General manager John Elway said he was saddened and disappointed in Kubiak's resignation, "but I understand and respect Gary for doing what's right for him and his family."
Elway now embarks on his third head coaching search in his six seasons as Broncos GM.
Vikings: Peterson says he'd consider pay cut
EDEN PRAIRIE, Minn. -- Adrian Peterson says he believes he's fit to play several more seasons in the NFL, even if that's elsewhere from Minnesota.
The 31-year-old Peterson finished his 10th season with the Vikings with only 72 yards on 37 rushes over three games.
After surgery on the torn meniscus in his right knee, Peterson returned for one game only to be sidelined again for the last two weeks because of an aggravation of the injury.
Peterson said Monday he was unable to play, even if the Vikings remained in contention for the playoffs.
Carrying an $18 million salary cap hit on his contract for 2017, Peterson is uncertain to come back at his age with the team's other needs. He said he'd consider a pay cut to return.
Panthers: DT Short would 'probably' sign franchise tag
CHARLOTTE, N.C. -- Panthers defensive tackle Kawann Short said he would "probably" sign a franchise tag offer if the team extended him one this offseason.
Short, who just wrapped up his fourth NFL season, will become an unrestricted free agent on March 9.
"I wouldn't fight it or anything," Short said of the franchise tag.
The Panthers tried to lock up Short to a long-term contract last offseason, but couldn't come to terms on an agreement in part because the $17 million-a-year contract that Fletcher Cox received from the Philadelphia Eagles raised the asking price for high-level defensive tackles.
Short wound up playing the 2016 season under the final year of his rookie contract.
Raiders: Team signs QB Gilbert to practice squad
ALAMEDA, Calif. -- The Oakland Raiders have signed quarterback Garrett Gilbert to the practice squad ahead of their first playoff game in 14 years.
Agent Leigh Steinberg announced the move on his Twitter account Monday. Gilbert spent time on the Raiders practice squad last season and was cut by the team in the offseason.
The Raiders were seeking a quarterback familiar with their offense with starter Derek Carr sidelined with a broken leg and backup Matt McGloin's status in question with an injured left shoulder. That leaves rookie Connor Cook as the only healthy quarterback under contract.
