The NFL says reported concussions rose 58 percent in regular-season games to the highest number in any of the past four years.

The league issued its concussion data for 2015 on Friday, a little more than a week before the Super Bowl, but did not release any data about total injuries.

According to the NFL, there were 182 reported concussions from 2015 regular-season games, reversing a recent downward trend. There were 115 in 2014, 148 in 2013, and 173 in 2012.

NFL Senior Vice President of Health and Safety Policy Jeff Miller says Friday the league is trying to figure out why concussion numbers rose so much this season.

Jets get positive review

Jets owner Woody Johnson gives his team positive reviews following its first season under coach Todd Bowles and general manager Mike Maccagnan, saying “so far, so good.”

The Jets finished 10-6 but missed the playoffs after losing at Buffalo in the regular-season finale. Still, Johnson says it was a good season, although “it’s not where we want to be.” He adds that the loss to the Bills still stings, but the franchise now needs to focus on the future.

Johnson was speaking Friday night at Jets House, a Manhattan restaurant the team has converted for two days into a meeting place for fans and current and former players.

The owner is noncommittal, as expected, on re-signing scheduled free agents such as quarterback Ryan Fitzpatrick and defensive end Muhammad Wilkerson.

Kelce signs extension

A person familiar with the situation says Kansas City Chiefs tight end Travis Kelce signed a $46 million, five-year extension that includes $20.5 million guaranteed.

The person spoke to the Associated Press on condition of anonymity Friday because the Chiefs did not disclose the terms of the contract in announcing the extension.

Kelce, a former third-round draft pick of the Chiefs, was entering the final year of his rookie contract. The 6-foot-5, 260-pound tight end has started 27 of the 33 games he’s played over three seasons, catching 139 passes for 1,737 yards and 10 touchdowns.

He missed the majority of the 2013 season after undergoing knee surgery.

Jaguars owner hopes to win

Jacksonville Jaguars owner Shad Khan says a winning record in 2016 is “everybody’s reasonable expectation at this point.”

Khan gave coach Gus Bradley and his staff one-year contract extensions last week, keeping them under contract through 2017. But speaking at a state of the franchise briefing Friday, Khan made it clear that on-field results have to improve for the current regime to stick around beyond next season.

When asked what he would like to see next season, Khan said, “Well, I think obviously better than 5-11. We want to have a team that is sustainable and wins. We’ve spent time, patience and investment to build a solid foundation that’s going to last for a long time.”
