After the Bears' final game of the 2016 season, Jeffery made a bold guarantee, saying that the team would win a championship.
"I guarantee you we are going to win a Super Bowl next year," he said.
Of course, Bears fans know how that turned out, as the team opted not to re-sign him, allowing him to sign a contract with the Eagles.
After Jeffery caught three passes for 73 yards and a touchdown in the Eagles' 41-33 win over the New England Patriots, the team tweeted out a reminder of the receiver's guarantee:
Maybe next year, Bears fans.
