Sanders is fourth on the team with 18 catches for 243 yards and two touchdowns. He started two weeks ago when Hines Ward was out with an ankle injury. He missed Sunday's loss against the Baltimore Ravens following his mother's death earlier in the week.
Ward is "doing well" with concussion-like symptoms and is not expected to be limited this week, Tomlin said. Ward left Sunday night's loss in the second quarter after a helmet-to-helmet hit from linebacker Ray Lewis.
"It shouldn't prohibit him or slow him down in any form or fashion here," Tomlin said.
