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 Womens John Elway Jersey , appeared to momentarily be knocked out (or close to it), 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, Jack signed a four-year, $57 million extension. When Tim Tebow announced that he would play minor league baseball, most people thought it was somewhere between a joke and a publicity stunt: The 31-year-old Tebow hadn’t played since high school. It just wasn’t realistic to think he could amount to anything after so much time off.But Tebow, to an extent, proved the doubters wrong. Although he was far from the best player in Double-A baseball last year, he was at least respectable, and looked like a legitimate baseball player. This was no publicity stunt.Unfortunately Bradley Chubb Broncos Jersey , Tebow has moved up to Triple-A this year, and the early returns are ugly.The stats for the Syracuse Mets, Tebow’s team, tell the story. He’s last on the team with a .120 batting average, last with a .185 on-base percentage and last with a .200 slugging percentage. He has struck out a team-high 10 times and hasn’t hit a home run.“He’s still learning how to hit some of this pitching,” Syracuse manager Tony DeFrancesco told ESPN. “I mean, these guys are throwing 97, 98 miles per hour. They’re spinning the baseball. He’s making some adjustments.”A 31-year-old minor leaguer who’s “still learning” wouldn’t last if he weren’t Tim Tebow, so there’s no doubt that the Mets organization is giving him a longer leash than it would most players. But he’s going to have to learn soon, or else his hopes of making it to the majors will go from slim to none.
