Gilbert, who got hurt Friday night against the New Orleans Saints, intends to get an independent evaluation from Dr. James Andrews out of Birmingham, Alabama, to determine whether he needs offseason surgery.
Gilbert classified the injury to his left elbow as "something I can play through," and he hopes it heals over time.
"I'll be there no matter what," Gilbert said about the Monday Night Football season opener Sept. 12 against the Washington Redskins. "No way I'm missing that first game."
Hyperextended elbows typically involve a strained or torn ligament. Gilbert won't confirm the exact nature of the injury, which resulted from Gilbert tossing his helmet toward the sideline in the first half of the team's 27-14 win in the Superdome.
Gilbert signed a five-year, $30-million extension in 2014 and has been a steady presence on a quality Steelers line. He garnered Pro Bowl consideration for his play last season.
The Steelers restructured Gilbert's contract last week to save about $2 million in salary cap space. Gilbert gets part of his 2016 salary in the form of a signing bonus.
