Boswell is 10 of 16 on field-goal tries this season and has missed five extra points for Pittsburgh, which will bid to snap a three-game skid on Sunday (4:25 p.m. ET) against the New England Patriots (9-4)
"We acknowledge that Chris has struggled. He has struggled to find consistent footing," Tomlin said. "We are willing to explore options that give us the best chances of the ball going through the uprights this week. That being said, those options include Chris."
Boswell earned his first Pro Bowl selection in 2017 by converting 35 of 38 field-goal attempts, including all four chances from beyond 50 yards.
The 35 field goals established a franchise record and marked the first time a Steelers kicker converted at least 30 attempts since Shaun Suisham in 2013. Not only was Boswell's 92.1 percent success rate a career high, but he also was 37 of 39 on extra points to finish with 142 points -- also a Pittsburgh single-season record.
This season hasn't gone as well for the 27-year-old Boswell, whose troubles caught the ire of former Steelers running back Rocky Bleier on Monday.
"Boswell. Now the purpose of a kicker is just to put his team in a position to win. If you can't do that, then maybe you need to go," the 72-year-old Bleier said on Facebook.
