ALLEN PARK -- A penalty call is a teaching moment for Jim Schwartz, but the Detroit Lions coach didn't know what to say to defensive tackles Ndamukong Suh and Nick Fairley after a pair of questionable flags in the fourth quarter.

The infractions, which have been panned by national broadcasters and columnists, played a big role in the Eagles game-tying drive early in the final quarter.

On second-and-10 from the Eagles 45-yard line, quarterback Nick Foles tried to connect with receiver DeSean Jackson on a deep pass, but overthrew the intended target. As Foles released the ball, he was drilled by Fairley with a shot that appeared to be legal, but the defensive tackle was flagged for roughing the passer.

"This one, he's trying to hit him in the midsection, he's getting his helmet out of the way, he's not late," Schwartz said. "He's almost simultaneous with the pass."

Had the call not been made, the Eagles would have faced third-and-10. On the day, Philadelphia went just 3-12 on third-down conversions. Instead, they were awarded a fresh set of downs.

Two plays after Fairley's roughing call, running back LeSean McCoy burst through the line for a 40-yard touchdown.

The Eagles failed on its two-point conversion attempt, but Suh was penalized for defensive holding. Again, based on replays, it's difficult to understand why the flag was thrown. Philadelphia punched it into the end zone on the second attempt to knot the game.

Schwartz was at a loss for words after the drive.

"It's difficult because one of our things we try to do with penalties is try to learn," Schwartz said. "In these cases, I honestly don't know what to tell Nick Fairley or Suh on those plays."

It's standard procedure for the team to have discussions with the league after games, but Schwartz doesn't expect to conversation to lead to any teachable moments for his players.

"Those two plays are difficult because it's hard to tell those guys what to do any different," Schwartz said. "I'd be surprised if the league had a different stance on that."

The Lions were able to immediate stem the Eagles' momentum when return man Jeremy Ross returned the ensuing kickoff 98 yards for a touchdown, but after that, it was all downhill for Detroit's defense.

Despite frustration over the penalty calls, Schwartz emphasized they wasn't the reason the Lions lost.

"We can't blame any of our tackling problems in the fourth quarter on any of those calls."
