From there the game was turned over to Boyle, who started hot. He directed two straight touchdown drives to get the Packers out to a 21-10 lead.

Boyle capped a 78-yard drive with a 1-yard TD flip to tight end Robert Tonyan, and then running back Aaron Jones finished the second march with a 1-yard scoring plunge. Jones, who is suspended for the first two games of the regular season, had nine carries for 34 yards in his last action until Week 3.

Tonyan had an 11-yard grab over the middle before his TD and a 15-yard catch to start another drive, making a run at a roster spot at one of the Packers' deepest offensive positions.

"Robert had some really good quality snaps in the first half. You could really see him and Tim connected very well, those guys have done that throughout all training camp," McCarthy said. "Tim feels very comfortable throwing the ball to him."

Boyle's night took a rough turn after those first two drives, though, as he finished 15-of-31 for 127 yards with the one TD pass and two interceptions, both in the second half.

The second pick was returned 30 yards for a touchdown by former Packers cornerback Makinton Dorleant, finishing a run of 23 straight Kansas City points to close the game.

"The focus was to get Tim Boyle as much work as possible," McCarthy said. "It's good tape to evaluate and learn from.
