New York Giants running back Tyrone Tracy Jr. is expected to be sidelined two to four weeks with a dislocated shoulder suffered early in the team's latest loss Sunday, sources told ESPN's Adam Schefter. Tracy, a second-year back, went down in pain when he was sandwiched by a pair of Kansas City Chiefs defenders on the second play of the second quarter. With Tracy out, the 0-3 Giants are expected to lean on rookie Cam Skattebo and veteran Devin Singletary to run the ball.
