MIAMI — Dolphins running back Reggie Bush limped off the field with 23 seconds left in the first half of Miami’s game against the New York Jets on Sunday with an apparent left knee injury.

Bush had 61 yards on 10 carries, the last coming on a first-and-10 from the Miami 20. He was tackled and rolled over once, grabbing at his left knee before being tended to by trainers.

Followed by members of the team’s medical staff, Bush left the field through one of the former baseball dugouts at Sun Life Stadium, which is closer to the Dolphins’ sideline than the end-zone tunnel.

Bush entered the day second in the NFL with 241 rushing yards, second only to Buffalo’s C.J. Spiller, who was injured against Cleveland earlier Sunday.
