The Kansas City Chiefs have acquired Cam Erving from the Cleveland Browns for a fifth round pick in 2018.

Erving was a first round pick on the offensive line in 2015.

From 2007 through 2016 the Browns took 13 players in the first round of the draft. Three are still with the team.

The Chiefs are set in their starting lineup at both tackle positions, right guard and center for the foreseeable future, with all four players being signed at least through 2018. The only opening for Erving in the starting lineup would possibly be at left guard; last year's starter, Parker Ehinger, has yet to play in the preseason after tearing his ACL last year.

Spencer Ware will miss the entire 2017 season due to a torn PCL and LCL.

Ware will undergo surgery and faces a lengthy recovery period.

The Buffalo Bills have traded Reggie Ragland to the Kansas City Chiefs for a 2019 fourth round pick.

Ragland tore his ACL in training camp in 2016.

Ragland was picked in the second round in 2016.

Spencer Ware has been carted off the field during Friday's preseason game with a right knee injury.

Ware took an awkward step right his right leg after catching a 6-yard pass from Alex Smith.

Ware rushed for 921 yards and had another 447 yards receiving last season for the Chiefs.

Ware was ranked in Tier 4 of RealGM's Fantasy Football preview, but he figured to share reps with Kareem Hunt.

The Kansas City Chiefs have promoted Patrick Mahomes II to backup quarterback behind Alex Smith.

Tyler Bray was dropped to No. 3.

Andy Reid said the move was one that Mahomes earned and not something the Chiefs would have done regardless of how he played.

"It's not because of Tyler's performance in the game," Reid said of Bray, who threw an interception in his first series Friday against the San Francisco 49ers. "I thought he actually did very well ... and Patrick did a nice job, too. It gives [Mahomes] an opportunity to step up and work with that second group and see what he can do there.

"It's not something [Tyler] didn't do. [Tyler] is playing well. But Patrick has also done a nice job. In order to step up with that group, Pat would have had to [make] progress."

Brandon Flowers told the NFL Network that he plans to announce his retirement Tuesday.

Flowers, who turned 31 in February, played the past three seasons with the San Diego Chargers after beginning his career with the Kansas City Chiefs.

The Chargers released Flowers in March, freeing up $7 million in cap space.
