Coach Mike Tomlin, however, didn't seem too concerned about the running back's status this week.
Tomlin told reporters Tuesday that Conner will have the chance to practice on Wednesday, which should "lay those discussions to bed," per NFL Network's Aditi Kinkhabwala.
In simpler terms: Conner must work out before he's officially cleared from concussion protocol, and his first chance to do so will be Wednesday.
For the season, the second-year back has been a dual-threat monster, gobbling up 771 rushing yards, 387 receiving yards and 11 total touchdowns in nine games.
Here are the other injuries we're monitoring this Tuesday in the NFL:
- New England Patriots tight end Dwayne Allen suffered a knee injury Sunday vs. Titans that will not require surgery but is expected to sideline him a few weeks, NFL Network's Michael Giardi reported. Rob Gronkowski (back, ankle) is expected to return to action following New England's bye week, however.
- Philadelphia Eagles tight end Richard Rodgers has been cleared to return to practice, the team announced. Rodgers suffered a knee injury in a preseason game and was placed on Injured Reserve in September.
- Los Angeles Rams receiver Pharoh Cooper has been cleared to return to practice. The team designated him to return from injured reserve on Tuesday. Cooper suffered an ankle injury in Week 1 and underwent surgery thereafter.
