Tampa Bay's struggling defense will be without middle linebacker Kwon Alexander for

the remainder of the season.The fourth-year pro was injured during the first half of Sunday's 26-23 overtime victory over the Cleveland Browns.A MRI performed Monday confirmed that the 24-year-old Womens Customized Cleveland Browns Jerseys , a fourth-round draft pick in 2015, has a torn anterior cruciate ligament in his left knee."It's unfortunate," coach Dirk Koetter said. "Kwon was playing so well, and was the heart and soul of our defense."Koetter said backup linebacker Jack Cichy also suffered a season-ending knee injury against Cleveland and will miss the remainder of the year."Our locker room at halftime was extremely emotional," Koetter said. "Kwon came out of the training room right about the time we were getting ready to go back on the field. It was emotional. You could tell guys really care (about him)."Alexander has started all 46 games he's appeared in during his NFL career. He was a Pro Bowl selection two years ago and was having one of his best games of the season when he took an awkward step while rushing the passer and tumbled to the ground in the final minute of the second quarter.He walked off the field and to the locker room without help, but he did not play the second half."Guys like Kwon mean everything to this team, and I have empathy for him," quarterback Jameis Winston said."Before we left out there for halftime, he was like: 'Never take anything for granted.' He's so right Baker Mayfield Jersey Elite ," Winston added. "We see the passion he plays with. We see the heart he puts in the locker room. ... We're going to miss him, and I know he is going to make an amazing comeback."Losing Alexander and Cichy will severely test a unit that was criticized for its play during a three-game losing streak that followed a 2-0 start.Cornerback Vernon Hargreves III and safety Chris Conte were placed on injured reserve in September. First-round draft pick Vita Vea missed most of training camp and the start of the season with a calf problem, and four other players tackles Gerald McCoy and Beau Allen, end Vinny Curry and cornerback Brent Grimes have missed at least one start because of injuries.With Tampa Bay sitting at or near the bottom of the league in several key categories, including points allowed, defensive coordinator Mike Smith was fired last week and replaced by linebackers coach Mark Duffner.The defense was sharper in its first game under Duffner, sacking Baker Mayfield five times and yielding a season-low 305 yards to the offensively challenged Browns."You've got to have a next-man-up mentality. Kwon is a key piece to this defense," linebacker Lavonte David said, adding that several reserves stepped up and played well while filling in for McCoy http://www.clevelandbrownsteamonline...ayfield-jersey , Curry and Alexander against Cleveland."Those guys ... filled the void, and that's what you've got to do," David added. "You never know when your number's going to get called, and their numbers were called (Sunday)." Denver Broncos tight end Jake Butt tore his left ACL during a walkthrough practice Thursday and is headed for injured reserve for the second straight season.Butt spent his rookie season last year on IR while recovering from the same injury to his other knee."Jake has worked his tail off to recover from his previous injuries, and we feel terrible for him," coach Vance Joseph said in a statement after an MRI confirmed the team's fears ."He's a great kid who's developed into a very good football player. We have no doubt Jake will come back stronger than ever," Joseph added.So, the Broncos (2-1), who host Patrick Mahomes and the Kansas City Chiefs (3-0) Monday night Authentic Baker Mayfield Jersey , find themselves waiting for Butt to get healthy once again.Butt had eight catches for 85 yards this season in his comeback from his last knee injury. He also tore his right ACL in spring drills as a sophomore at Michigan.That medical history helped drive his draft stock down last year, making him the forgotten member of 2017's deep tight end class even though he won the John Mackey Award as the nation's top tight end his senior season.Many teams considered Butt as talented as first-round selections O.J. Howard, Evan Engram and David Njoku, but he slipped to the fifth round after tearing his right ACL in Michigan's 33-32 loss to Florida State in the 2017 Orange Bowl. He was the eighth tight end drafted last year.Butt had a solid offseason and took most of the first-team snaps while Jeff Heuerman missed two weeks of training camp with a sore knee.Butt's injury leaves the Broncos with two fourth-year tight ends in Heuerman and Matt LaCosse, plus Brian Parker on their practice squad.
