TAMPA Customized Tampa Bay Buccaneers Jerseys , Fla. (AP) — Tampa Bay's struggling defense will be without middle linebacker Kwon Alexander for the remainder of the season. half of Sunday's 26-23 overtime victory over the Cleveland Browns.A MRI performed Monday confirmed that the 24-year-old, 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 www.authenticstampabaybuccaneers.com , he was like: ‘Never take anything for granted.' He's so right," 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 Tampa Bay Buccaneers T-Shirt , adding that several reserves stepped up and played well while filling in for McCoy, 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)."Is Tampa Bay’s offensive line becoming a concern? There was plenty of excitement in regards to Tampa Bay’s offensive line coming into the 2018 season. The additions of Ryan Jensen, a soon-to-be healthy Demar Dotson, and another small-time school standout in Alex Cappa were key in hopes to elevate the unit’s performance as a whole.All of a sudden after just a week and a half of training camp, that excitement has been dampened a bit due to injuries at a couple of key spots. First came backup tackle Leonard Wester, a contributor in 2017 and a player who had already turned a few heads in camp before getting injured on the first Saturday over a week ago. Caleb Benenoch - expected to take over after the Bucs cut J.R. Sweezy - missed another day as he sits out due to an undisclosed injury he suffered in last Friday’s practice. With the coaching staff being as cautious as ever with Dotson’s return from his knee injury Tampa Bay Buccaneers Hats , things currently look pretty grim for the Bucs’ right side of the line and Dirk Koetter knows this. “I would say it’s injured. I would say it’s injury riddled right now. I don’t think anything on the right side of our O-line is long term,” Koetter said after today’s practice. “We’ve just gotten hit hard at that spot. We’ve got three or four guys that play on the right side of the line that are not practicing right now. That tests your depth, so we have to work through it. They’ll all be back before too long. That helps those other guys get better, but in the mean-time we’ve got to tough it out.”The good news is that nothing seems to be long term, but for players like Benenoch, every rep is crucial to his development and it could play a key role in the unit’s overall performance during the season.Benenoch is missing valuable practice timeKim Klement-USA TODAY SportsAt least the Bucs have Evan Smith and an ever-developing rookie in Alex Cappa to help ease the pain. Smith rated as the 24th-best guard in 2017 with a good grade of 69.6 according to Pro Football Focus. He has started 56 games during both the regular season and the playoffs, so the experience and ability is there. Cappa was officially named Benenoch’s backup according to the depth chart the Bucs released today, but keep in mind that can change at any time during the preseason. But what if either of them go down with an injury? Even worse, what if Ali Marpet Tampa Bay Buccaneers Hoodie , Ryan Jensen, or Donovan Smith have to miss time?That would leave Cole Boozer, Brad Seaton - they were actually playing with the ones today due to injuries - Cole Gardner, Jerry Ugokwe, and others as the primary options for the Bucs. The players just mentioned have a combined three years experience in the league with no starts nor playing time during a NFL season. That my friends, is a reason to worry. Especially when these injuries could affect the entire offense as Koetter explained, stating that in order to combat the injuries, “we’ll just have to adjust accordingly and we might have to adjust the play calling accordingly.”So while things may not be so bleak at the mom, the potential for big issues at the position is there. The whole point of training camp and the preseason is to come out of the wash as healthy as possible. If these injuries are going to happen Youth Customized Tampa Bay Buccaneers Jerseys , it’s best they happen now. I’m willing to bet that the Bucs feel better off knowing what they have now depth-wise as they head into the season, but at the same time an offensive line needs time to gel and right now they aren’t receiving the necessary playing time in order to do that. Just like the Bucs 2018 season, it’s a juggling act right now on the offensive line - and yet another puzzle for the coaching staff to piece together.
