The NFL has implemented a temporary rule change that will prevent an instant replay of what happened earlier this season in a Giants-Eagles game. "Time remaining on the game clock will be reviewable but will be limited to situations in which time is deemed to have expired or not expired prior to, during or after the last play of the first or second half, or of an overtime half," according to a memo that NFL commissioner Roger Goodell sent to the 32 teams. The rule goes back to the Dec. 13 game between New York and Philadelphia. Just before halftime, Giants kick returner Domenik Hixon fumbled the football and Eagles linebacker Moise Fokou recovered, but the clock seemingly ran out. Replay evidence suggested there still was at least a second remaining, but replay rules did not permit the play to be reviewed.
