Steelers' Tomlin Explains Not Naming Justin Fields QB1 amid Russell Wilson's Injury

Despite Justin Fields' hot start to the season, Pittsburgh Steelers head coach Mike Tomlin still hasn't committed to him as the team's starting quarterback while Russell Wilson continues to recover from a calf injury.

When asked on Tuesday why he isn't naming Fields the starter, Tomlin told reporters, "Because there's no need, I explained to you the variables of the week. ... When Russ gets to an appropriate level of health, and I have a decision to make, I'll make it."

Fields, who was acquired from the Chicago Bears this past offseason, was expected to spend the year as Pittsburgh's backup quarterback behind Wilson. However, he was thrust into the starting role when Wilson reaggravated his calf injury late in training camp, and he's more than risen to the occasion.

Field has helped lead the Steelers to a 3-0 start thanks to his steady play. While his numbers of 518 yards, two touchdowns and an interception don't necessarily jump off the page, he's shown a level of poise that wasn't seen during his previous three years in Chicago. He's completing a career-high 73.3 percent of his passes and he's also added 90 rushing yards and another score.

The 25-year-old isn't getting too ahead of himself amid his hot start to the season, as he said after Sunday's win over the Los Angeles Chargers that he's not focused on proving his doubters wrong.

"I'm not really worried about that," Fields said. "I'm more so into proving myself right. I know what kind of player I am. I haven't changed my whole life, so at the end of the day, my teammates help me be great. So shout out to them -- shout out to our defense, shout out to everybody else on the offense for pushing me each and every day at practice. It's just a credit to them. So I'm definitely glad and just feeling good to be in this position, to be honest with you."

When Wilson is fully healthy, the Steelers' best course of action could be to keep riding with Fields until a switch is absolutely necessary.

Pittsburgh will look to move to 4-0 when it faces the Indianapolis Colts on Sunday.
