The Bills decided to keep him out of Thursday night's preseason finale against the Detroit Lions.
Bills coach Dick Jauron was asked after the 17-6 loss if Edwards wore a ballcap because there was nothing to gain.
"Very much so," Jauron said.
In those games, Edwards went a combined 13-of-24 for 76 yards and no touchdowns with two interceptions. He was sacked three times and lost a fumble.
"I felt that probably did him a disservice by not preparing him specifically for Green Bay and Pittsburgh," Jauron said. "We were in camp mode, and that's all we did. So I didn't want to do it a third time in a row.
"We started preparing Trent for New England and gave him all New England reps up to this game, and both just decided it was better not to put him in there again with no preparation for another opponent."
