No team has been hit harder by injuries than the Cleveland Browns. The Browns had 20 players on their estimated Monday injury report in preparation for Thursday night's home game against the Denver Broncos. Among those players are quarterback Baker Mayfield, who underwent an MRI on his left shoulder the day after Cleveland's 37-14 home loss to Arizona.

Mayfield will exercise his collectively bargained right to a second opinion with a doctor of his choosing.

The second opinion will take place before coach Kevin Stefanski can say whether or not Mayfield or Keenum will start Thursday night's game, according to Cleveland.com's Mary Kay Cabot. Obviously the short week comes at a bad time for the Browns with Mayfield and several of their key players on the injury report.

It's not a good start to the week for the Browns who host the Broncos on Thursday night. Beckham and Mayfield were also listed as did not practice. This will be something to monitor as the week goes on. With Kareem Hunt already out, the loss of Chubb would force Johnson and Felton into the lineup, perhaps both in significant roles. If Mayfield can't go, Keenum would get the start at QB.

Browns reached agreement with former Redskins' QB Case Keenum on a three-year, $18 million deal that includes $10 million guaranteed, per source.

Case Keenum has yet to show much since his magic season in 2017 with Minnesota, but the 32-year old keeps getting gigs. He'll provide some veteran leadership for Baker Mayfield and can keep things going if needed in Cleveland.

Haskins is expected to get an MRI and other tests on Monday. Rapoport said Haskins wants to play in the finale, but no indication yet on if he’ll be able to. He was 12 of 15 for 133 yards with 2 TDs pre-injury. Keenum would get the start if Haskins can't go.

Haskins told reporters that X-rays on his ankle came back negative, but he will undergo an MRI exam for further evaluation. Haskins added that he wanted to return to the game, but owner Daniel Snyder instructed him to sit out the remainder of the game. Washington could play it safe and go with Keenum in Week 17.

Redskins coach Bill Callahan said Dwayne Haskins will be the starter for the rest of the season.

The move makes sense for the rebuilding Redskins and should take some pressure off Haskins as he no longer has to wait iweek-to-week for an announcement. With not a lot of weapons around him, Haskins will be a borderline streaming option even on the best weeks.
