Week 18 is typically not the time of year when NFL teams are at their strongest health-wise. But that’s where the Ravens are as they returned to work Monday and began preparations for their regular-season finale against the Cleveland Browns on Saturday at M&T Bank Stadium.

Baltimore designated Charlie Kolar to return from injured reserve on Monday, clearing the way for the tight end who broke his forearm in late November to potentially play this week or possibly for the first round of the playoffs.

“This was kind of the target game when it happened,” coach John Harbaugh said. “We’ll see how he looks this week. Hopefully, he’s feeling good and ready to go.”

The Ravens have 21 days to activate Kolar or he would revert to season-ending injured reserve.

Baltimore’s top in-line tight end, Kolar also contributed in the passing game before getting injured in Baltimore’s Nov. 25 win over the Los Angeles Chargers at SoFi Stadium in Inglewood, California. In 12 games (three starts), he has nine catches for 131 yards and a touchdown while averaging just over 19 snaps per game on offense and playing a key role on special teams.

He’s not the only player the Ravens will be getting back, either.

Running back Justice Hill, who has been out since suffering a concussion in Baltimore’s win over the Pittsburgh Steelers on Dec. 21, missed Monday’s practice because of illness but is expected to be back Tuesday and will play against the Browns, Harbaugh said. Baltimore was briefly down to two running backs — Derrick Henry and Keaton Mitchell — during last week’s game against the Texans after rookie Rasheen Ali left with a hip injury.

Meanwhile, left tackle Ronnie Stanley and left guard Patrick Mekari were absent from Monday’s practice because they had “flu-like” symptoms, according to Harbaugh, but likewise are expected to return Tuesday.

“Up to this point we’re really happy with where we’re at with that,” Harbaugh said about the team’s health. “I do think a lot of work has gone into it.

“It’s definitely fueled our success, for sure. It’s something that’s a big deal in the National Football League, so we’re happy with it. Hopefully, we can keep it going.”

Still, they’ll have to navigate one more win — and a short week of practice — to clinch the AFC North title for the second straight year and secure the No. 3 seed in the conference going into the postseason.

Saturday’s game comes after the Ravens played three games in 11 days — all wins. The NFL did not announce the Week 18 schedule until late Sunday night and Ravens players reported back to the team facility on Monday.

Harbaugh said it was an organizational effort when it came to getting through that gantlet.

“Everybody’s involved in that,” Harbaugh said. “Team effort, for sure.”
