The Ravens never expected three centers to suffer major injuries before October. At the beginning of the week, they didn’t expect Trey Hendrickson (finger) to be ruled out for Sunday’s game against the Tennessee Titans. But handling unexpected events is part of thriving in the NFL. Vega Ioane was selected in the first round to be Baltimore’s starting right guard, not its center. But with Danny Pinter, Jovaughn Gwyn and Ethan Pocic unavailable, Ioane’s role has changed and he is moving forward. Hendrickson can’t face the Titans, so Mike Green and undrafted rookie Ethan Burke will take on larger roles. That’s what it takes to win consistently. You find a way, even when things don’t go your way. Baltimore is a clear favorite against the winless Tennessee Titans (0-3) on Sunday, but that won’t matter after kickoff. The Ravens have lost four straight games at M&T Bank Stadium dating back to last season. They have learned the hard way that no game can be taken for granted. “I think that’s something that in this league sometimes you can lose,” safety Kyle Hamilton said. “When you watch college football, you see these big Power Four schools playing smaller teams. None of that happens in the NFL.” The young season has already produced a series of unexpected developments and wild endings. The Ravens need to avoid an upset by defeating the Titans on Sunday.
