With less than 30 seconds left in the second quarter, Chicago quarterback Mitch Trubisky appeared to complete a 30-yard pass to Anthony Miller, but it was initially ruled incomplete, as Eagles cornerback Cre'von LeBlanc pried it loose as both players were falling to the ground inside the 10-yard-line.
The replay shows that Miller did make the catch, taking at least two steps before going to the ground with full control of the ball before fumbling it. Under the NFL's new rule this year, that would be a catch.
"When a pass is ruled incomplete, either team can challenge that it was a catch and fumble and that they gained possession of the ball, if there is a clear recovery. The replay official can also initiate a review of this play if it occurs after the two-minute warning or during overtime. If there is video evidence of a clear recovery by either team, the ball will be awarded to that team at the spot of the recovery, but no advance will be allowed. On fourth down or inside two minutes, the ball will be brought back to the spot of the fumble if recovered beyond it."
The key sentence then follows: "If there is no video evidence of a clear recovery or the ball going out of bounds, the ruling of incomplete stands."
