BEREA Cleveland Browns Hoodie , Ohio (AP) — Cleveland’s defense took another big hit.A day after giving up 246 yards rushing, the Browns learned they may be without Pro Bowl linebacker Joe Schobert for several games because of a hamstring injury.Schobert got hurt in the third quarter of Sunday’s 38-14 loss to the Los Angeles Chargers, and coach Hue Jackson said Monday he will be “down for a little while.”Jackson could not provide a time frame on Schobert.“How long that will be, let’s go week to week with that and see where he is,” Jackson said. “Hamstrings are tricky. Some last longer. Some end up shorter. We will see how all of that unfolds.”Cleveland’s defense can’t afford to lose Schobert, who tied for the league lead with 144 tackles last season and hasn’t missed a defensive snap since the start of 2017. He’s also the defense’s “quarterback,” calling the formations called in by coordinator Gregg Williams.Schobert was replaced by James Burgess Jr. https://www.brownsfanshop.com/James-Burgess-Jersey , who injured his hamstring in the fourth quarter and likely will sit out this week’s game at Tampa Bay. Jackson said Christian Kirskey could slide over from outside linebacker to take Schobert’s spot.Also, Browns wide receiver Rod Streater suffered a neck fracture while covering a punt Sunday and is done for the season. Streater got hurt in the first quarter in the latest blow for Cleveland’s injury-depleted receiving unit.Streater was expected to get more playing time while Rashard Higgins (knee) and Derrick Willies (collarbone) recover from their injuries.The Browns said Streater is “doing well” and team doctors expect him to make a full recovery. Streater does not need surgery at this time.Willies had an operation Monday after he broke his collarbone during practice on Friday. The team remains hopeful Willies will return at some point in 2018.The injury situation could force the Browns to sign another wide receiver or make a trade. The team signed free agent Breshad Perriman on Saturday, but he did not have enough time to learn the offense and was inactive Sunday. Johnny Football is heading to Memphis to resume his football career.Johnny Manziel signed with the Alliance of American Football on Saturday night and will join the Memphis Express. The quarterback’s rights belonged to San Antonio of the spring league, but that team declined to sign him and Manziel then was free to join any of the other seven clubs. He was awarded through the AAF’s waiver system to the Express, who have a league-worst 1-5 record.“We are pleased to welcome Johnny Manziel to Alliance of American Football, which we’ve always described as a league of opportunity for talented players to launch or revitalize their pro football careers,” Alliance co-founder Bill Polian said in a statement released by the league. “We completed extensive background work to determine whether it would be appropriate for Johnny to play this season Jim Brown Color Rush Jersey , and after consulting with many people familiar with his situation, we concluded that it would be good for him to resume his pro football career here at The Alliance.”Manziel is expected to report to the Express on Sunday.“Welcome to the 901 @JManziel2,” the team wrote on its official Twitter page.The 2012 Heisman Trophy winner at Texas A&M had his contract with the CFL terminated this offseason. The Canadian league said he violated his agreement with it, but has offered no specifics.Manziel was a first-round draft pick by Cleveland in 2014, but quickly fizzled out there with seven touchdowns and seven interceptions in 14 games, including eight starts. The Browns released him in March 2016He was 2-6 as a starter with the Montreal Alouettes last season, completing 106 of 165 passes (64.2 percent) for 1 Jamie Collins Jersey ,290 yards with five TDs and seven interceptions. He also ran for 215 yards on 29 carries as Montreal (5-13) missed the CFL playoffs.In Memphis, Manziel could get an opportunity to play quickly. Express quarterback Zach Mettenberger injured an ankle Saturday on the first play from scrimmage and was unable to return to the team’s 22-9 loss at Salt Lake. He was replaced by Brandon Silver, who went 23 of 37 for 242 yards and one touchdown with one fumble.The status of Mettenberger, who had replaced Christian Hackenberg as Memphis’ starter, was uncertain so coach Mike Singletary could look to Manziel to lead his squad down the stretch. Hackenberg remains on the roster, but is 32 of 62 for 277 yards with no TDs and three interceptions.
