The reigning Super Bowl champion Seattle Seahawks were dealt a big blow on Friday.Wide receiver Jake Bobo was carted off the field during the team’s joint practice with the Tennessee Titans, and head coach Mike Macdonald called it a "serious" injury."Our heart goes out to Jake Bobo," Macdonald told reporters. "It seems like it's going to be a serious knee (injury). We're going to get it imaged, but early returns are (that) it looks like it's a long-term injury. That's unfortunate."The 28-year-old wide receiver got hurt along the sideline and needed help to get onto the cart. Players from both teams took a knee, while Macdonald said the team prayed for Bobo. His right leg was outstretched on the cart."It hurts, man," Sam Darnold said of Bobo’s injury. "He's one of those guys that he works, he talks a lot of stuff and he's kind of like (Devon Witherspoon) in a way, offensively. He brings the juice every single day, and he just does his job. So it sucks to lose Bobo but I know he's going to attack it and be better whenever he comes back."ZERO BS. JUST DAKICH. TAKE THE DON'T @ ME PODCAST ON THE ROAD.
