Pro Bowl wide receiver Zay Flowers was missing at practice Tuesday as the Ravens started their preparation for Saturday’s playoff opener against the Pittsburgh Steelers.

Flowers, who led the offense in catches (74) and receiving yards (1,059) in the regular season, suffered a knee injury Saturday in the Ravens’ win over the Cleveland Browns, which clinched an AFC North title and a home playoff game in the wild-card round.

Coach John Harbaugh said after the game that the injury is “something that he has a chance to be OK with,” then clarified Monday that it would not be season-ending.

“It’s just going to be day to day,” Harbaugh said. “He’s going to try to do everything he can do to get back as soon as he can, and we’ll see where that takes us.”

Flowers had two catches for 39 yards and a touchdown in the Ravens’ Week 11 loss in Pittsburgh, 18-16, then had five catches for 100 yards in their Week 16 rematch, a 34-17 win.

He was also the Ravens’ leading receiver in both of their playoff games last year, making four catches for 41 yards in a divisional-round win over the Houston Texans, then five catches for 115 yards and a touchdown against the Kansas City Chiefs in an AFC championship game loss.

Running back Justice Hill, who’s missed the past two games because of a concussion and illness, returned to practice Tuesday as a limited participant. Though Hill was working out in a non-contact pinny, he’s expected to be available Saturday.

Safety Kyle Hamilton (knee) was also limited Tuesday.

Note: Wide receiver-returner Deonte Harty, who’s played in just five games for the Ravens and last appeared in Week 6, was designated to return off injured reserve Tuesday and was a full participant in practice. The Ravens have cycled through punt returners since losing Harty to a knee injury in October. He has returned four kickoffs for 98 yards and eight punts for 85 yards this season.
