Chiefs turn to CB Revis for help

Bills coach McDermott switches back to Taylor as starting quarterback.

The Chiefs have signed veteran cornerback Darrelle Revis in their latest attempt to shore up their porous defensive backfield, though it is unclear when he’ll be ready to play.

The Chiefs announced the signing Wednesday, four days before they face the Bills.

Revis, who had been a free agent after playing for the Jets last season, is a seven-time Pro Bowler and at one point was widely considered the best cornerback in the league.

He had 29 interceptions over 10 seasons and won a Super Bowl with the Patriots.

The Chiefs have tried Terrence Mitchell, Kenneth Acker, Steven Nelson and Phillip Gaines at the cornerback spot opposite Marcus Peters this season.

Bills: Coach Sean McDermott reversed course, saying quarterback Tyrod Taylor will start at Kansas City on Sunday, a week after his decision to start rookie Nathan Peterman backfired.

McDermott called his decision to return to Taylor “the right thing for our team,” after Peterman threw five interceptions in a 54-24 loss at the Chargers.

Taylor, who is 20-18 in 2½ seasons in Buffalo, was benched after going 9 of 18 for 56 yards in a 47-10 loss to the Saints on Nov. 12.

Peterman is a fifth-round pick out of Pittsburgh who became the first quarterback to throw five interceptions in the first half since the AFL-NFL merger in 1970.

McDermott shook his head “No,” on Wednesday when asked if he had any regrets about starting Peterman.

Patriots: Quarterback Tom Brady sat out Wednesday’s practice with what the team says is an Achilles tendon injury. Brady has started all 10 games this season.

49ers: San Francisco fans will continue to wait for a look at Jimmy Garoppolo.

Coach Kyle Shanahan announced rookie C.J. Beathard will remain the team’s starting quarterback for Sunday’s game against the Seahawks.

Texans: Placed rookie running back D’Onta Foreman on injured reserve and claimed veteran back Andre Ellington off waivers from Arizona. Foreman ruptured his left Achilles tendon Sunday during a touchdown run against the Cardinals.

Foreman rushed for 327 yards and two touchdowns on 78 carries as backup to Lamar Miller.

Lions: Claimed veteran pass rusher Dwight Freeney a day after he was released by the Seahawks. The 37-year-old was not active for Thursday’s game against the Vikings.

Freeney had three sacks in four games with Seattle.
