Bell has yet to sign his $12.12-million franchise tender and is not subject to fines as a result. Both sides couldn't reach a long-term agreement before the July 17 deadline, which Bell told ESPN was "a little frustrating, but it's a business."
Antonio Brown reiterated to reporters what he said on social media in a direct message to Bell: The first part of getting better is showing up.
"When trying to do something special, we would like all our guys here," Brown said.
Other players took a softer approach, acknowledging they would like Bell in camp but understand the business side. Left tackle Alejandro Villanueva, who was also without a contract, reported to camp after the Steelers signed him to a four-year deal Thursday afternoon. Bell has precedent with Chiefs safety Eric Berry, who last season reported later in August to sign his tender, then had a big year and signed a six-year, $78-million extension this offseason.
"It's a tough part of it, but it's an essential part of it," guard David DeCastro said. "The biggest thing with the football, no matter who you are, this thing moves on without you. It's kind of an unfortunate truth but it is the way it is. If he's not here, we've got to go."
Center Maurkice Pouncey says Bell is a unique talent who doesn't need practice every day, but the benefit of reporting is "just to be around the team, so you guys don't have to ask the same questions every day. He could sit on the sidelines and answer those questions."
In other Steelers news, wide receiver Martavis Bryant is not eligible to practice because he's still under conditional reinstatement with the NFL over substance abuse violations.
Bryant has missed 20 games the last two seasons for drug offenses. In late April, the league made clear he could be with the team on a conditional basis and had hurdles to clear.
A source says Bryant is with the team right now and is working to finalize his reinstatement in the coming days or weeks.
"Upon his conditional reinstatement in April, Martavis Bryant was made aware it was only the beginning of a process toward a return to being a full contributing member of the Pittsburgh Steelers," general manager Kevin Colbert said in a statement. "We have been informed by the NFL that Martavis is still in the process of being fully reinstated. Until that time, Martavis will be permitted to take part in off-the-field team activities at training camp, but he will not be permitted to practice or play in any games."
