When the Steelers open minicamp today Daniel Jones Jersey , a strange thing will be happening.Via Joe Rutter of the , all the Steelers are expected to be on the field today, which is a departure from the past.Running back Le'Veon Bell skipped the last two years of minicamp before getting his freedom and joining the Jets. Antonio Brown skipped most of the voluntary work last year Dexter Lawrence Jersey , but showed for minicamp.But with those two no longer occupying all the oxygen, things have been peaceful. The only player not under contract is cornerback Mike Hilton, who hasn’t signed his exclusive rights tender yet. But he’s shown up throughout the offseason.Veteran guard David DeCastro was the only player to miss OTAs Deandre Baker Jersey , after his wife gave birth to their second child, but he is expected today.Which means the Steelers can focus on football. For a change. Jacksonville’s Thursday night win included a moment that created some concern for linebacker Myles Jack.The fourth-year defender took a knee to the helmet in the second half, appeared to momentarily be knocked out (or close to it) Oshane Ximines Jersey , and exited the game. He did not return.Jack has entered the concussion protocol. The mini-bye after the Thursday night game gives him some extra time to recover before the team’s Week Four game in Denver; he won’t be able to practice or play until he receives clearance from both team doctors and an independent neurologist.When the NFL first became serious about concussions a decade ago, placement in the protocol often meant missing at least one game. More recently, it seems that plenty of players end up cleared to return by the next game.It was the second early exit Jack has made this season. He was ejected from the Week One loss to the Chiefs. Before the season started Julian Love Jersey , Jack signed a four-year, $57 million extension.
