This night could not get much worse for the Jets.

They began the Monday night game without linebacker C.J. Mosley (groin) Browns Customized Color Rush Jerseys , defensive tackle Quinnen Williams (ankle) and quarterback Sam Darnold (mono). They trail the Browns 13-3.Now, backup quarterback Trevor Siemian is hurt.Luke Falk entered the game with 7:44 left in the half as Siemian limped into the locker room with a lower leg injury that did not look good.Siemian was injured on a roughing the passer penalty on Browns defensive end Myles Garrett, his second 15-yard penalty of the night. Siemian’s left leg bent underneath him.The Jets promoted Falk from the practice squad last week.

The Cleveland Browns have officially designated cornerback Terrance Mitchell to return from injured reserve.Head coach Gregg Williams confirmed the expected news during a press conference on Wednesday, indicating Mitchell returned to practice and can return to games as early as Week 14 against Carolina.Mitchell was placed on injured reserve days after suffering a gruesome wrist fracture in Week 4 at Oakland. We thought he’d make it back by Week 14 Cleveland Browns T-Shirts , and so did he, saying he was “healing like Wolverine” a few weeks after the injury.With rookie Denzel Ward banged up and E.J. Gaines on injured reserve himself, the Browns secondary has had to improviserecently, but they have held their own. Either way, getting Mitchell back soon will be a big boost for the newly energized Browns. Williams is leading the team now, and they have responded with some spirited performances https://www.brownsfanshop.com/hats , albeit in a limited sample.Luckily, the Browns may not need Mitchell immediately. According to The Chronicle-Telegram’s Scott Petrak, the only Browns player missing practice coming out of the bye week has been center J.C. Tretter. Tretter hasn’t practiced at all and may be in danger of missing Week 12 in Cincinnati.Rookie receiver Derrick Willies is one to watch for the Browns’ second activation in the coming weeks. Willies broke his collarbone on Oct. 12 and had surgery three days later. He’s a candidate to return for Week 15 against Denver, so look for some potential news on him returning to practice in the next week or so. If not Willies, it’s unclear who the team would choose to bring back this season. Chris Kirksey and Gaines are both ineligible to return from injured reserve.
