Flowers (calf) was listed as a non-participant on Tuesday's estimated injury report.
Flowers kicked off Week 17 prep in the exact same situation, following it up with a true DNP and then logging a limited session before the Ravens considered him questionable for this past Sunday's game against the Dolphins. He was active though and he didn't look worse for wear en route to three catches on three targets for 106 yards and a touchdown. There's been no indication that Flowers is in danger of sitting out Saturday versus the Steelers, but with Baltimore having nothing to play for and locked into the top seed in the AFC for the playoffs, they may be more cautious this time around with the rookie wideout.
