He broke it in the Steelers' Week 4 loss to the Vikings, and has missed the wins over the Jets and Ravens.
Derek Moye had a catch and nearly his second career touchdown last week, earning a helmet in Wheaton's absence. Veteran Jerricho Cotchery has performed well in the opportunity he's had as well.
Tomlin said he's "optimistic" about the chances of right tackle Marcus Gilbert returning to the lineup. He played seven snaps against the Ravens before being removed due to the quadriceps injury he previously had. Guy Whimper filled in for him, and played well.
The team also reported Kelvin Beachum (ribs), LaMarr Woodley (knee), Brett Keisel (ribs) and Cam Heyward (illness) may be limited in the early practices this week, but none have been ruled out.
Keisel left Sunday's win over the Ravens in the fourth quarter and did not return. Woodley was limited in practice early last week as well.
