Justin Fields might be in his best groove yet in his second season as Chicago's quarterback.

Dak Prescott is trying to find his next one with the Dallas Cowboys in his second game back after missing five with a fractured right thumb.

The Bears face another tough road game against the Cowboys on a short week after winning in New England for the first time in franchise history.

Fields has a shot at his first back-to-back road victories Sunday after arguably his most complete performance during Monday night's 33-14 win over the Patriots.

Fields had 82 of Chicago's 243 yards rushing with a touchdown and was 13 of 21 for 179 yards passing with a TD and an interception as the Bears (3-4) moved the pocket and used designed QB runs.

Although the former Ohio State star struggled the previous game in a loss to Washington, he had career highs in completion rate (71.4%) and passer rating (118.8) in a Week 5 loss to Minnesota.

Prescott was understandably ragged early in a 24-6 victory over Detroit in his first game since breaking the thumb on his throwing hand in a season-opening loss to Tampa Bay.

But the 2016 NFL Offensive Rookie of the Year was 7-of-8 passing with a touchdown in the fourth quarter as the Cowboys (5-2) pulled away, once again leaning on one of the league's best defenses.

Prescott now faces the NFL's No. 2 pass defense, although the Bears gave up an important part of that group this week by sending defensive end Robert Quinn to Philadelphia, Dallas' undefeated NFC East rival.

The Bears are averaging a league-best 181 yards rushing per game. It's the first time since 1990 they've held the top spot through Week 7, and their 242 attempts are also more than any other team this season.

Chicago had its third 200-yard rushing game of the season against New England, with matching 62-yard showings from Khalil Herbert and David Montgomery to go with Fields' team-leading total.

Herbert is ninth in the NFL with 464 yards rushing and leads all NFL running backs with a 6.2-yard average (Baltimore QB Lamar Jackson is the overall leader).

Game time is noon Sunday.
