Wide receiver Torrey Smith is poised to leave the Ravens as a free agent, according to multiple NFL sources, and the San Francisco 49ers are the front-runners to land the former Maryland standout.

For Smith to have remained with the Ravens, which several league sources reiterated has been an extremely unlikely scenario for weeks, he would have had to leave several million dollars on the table.

Although no deal has been finalized, sources indicated there's strong mutual interest between the former second-round draft pick and San Francisco. One source characterized the Smith situation as a "done deal with the 49ers," barring any unforeseen snags. Deals cannot become official until Tuesday at 4 p.m., when the league year and free agency signing period begins.

Smith acknowledged his pending departure Sunday night with a blog in which he thanked the Ravens for his four years in Baltimore.

Update: Smith signed a five-year, $40 million deal that includes $22 million guaranteed.

Smith got off to a slow start in 2014, posting just six catches for 85 yards in the first three games. Over the final 13 games of the season, he averaged 3.3 receptions for 52 yards and 0.85 touchdowns, which equates to #20 WR-type numbers in PPR formats. As it stands, he finished as the #29 WR in PPR and #19 in standard formats (thanks to the high touchdown rate), which is the fourth time he has finished in the top 23 (in standard formats) in his four-year career. He'll join a 49ers receiving corps that is likely losing Michael Crabtree and has a still-effective Anquan Boldin as a possession receiver. Smith will serve as a deep threat for QB Colin Kaepernick, though this move has to be considered a downgrade from an offensive/quarterback standpoint since the 49ers are typically run-heavy and Joe Flacco is pretty adept at putting touch on the deep ball. Throwing with touch is not one of Kaepernick's strengths.

Ravens hired former Bears HC Marc Trestman as offensive coordinator, per source.

Trestman has had some terrific offenses over the years, including four top 10 units (49ers in '95 and '96, Raiders in '02 and the Bears in '13). His arrival bodes well for Joe Flacco and Justin Forsett (specifically in the passing game).

After a statistically down first half of the season, Torrey Smith had one of his better games in Pittsburgh Sunday night and feels he’s taking a better mental approach to the game.

Smith hauled in a 35-yard touchdown from quarterback Joe Flacco early in the first quarter and finished with four catches for 63 yards. It was one of his best games of the year.

“It is a mental thing the way I approach the game, the way I was attentive on the field,” he said. “I was definitely locked in on that. It is a brand new half of the season for me personally and I’m looking forward to making the plays that we need to get it done. And I have to do a lot more.”

Smith has four touchdowns in his last four games. He’s caught 11 passes for 195 yards during that span, which included being shut out in Cincinnati.

Through the first five weeks of the season, Smith was the #62 WR in fantasy football. Over the past four games, he is the #15 WR, gaining 195 yards and catching four touchdowns. That even includes a goose egg against a tough Cincinnati secondary.

Ravens TE Owen Daniels had a "clean-up procedure on his knee and will be out at least one game. Crockett Gillmore expected to start.

There isn’t much opportunity for fantasy owners here, as Crockett Gilmore is more of a blocking tight end. Fullback Kyle Juszczyk may see snaps at tight end as well. It certainly doesn't help QB Joe Flacco, who now has one fewer weapon in the passing game.

In a run-heavy offense that stresses safer passes for quarterback Joe Flacco, Torrey Smith was never a strong bet to repeat last year's production. After leading the team in 2013 with 65 catches and 1,128 receiving yards, though, he's on pace for just 453 yards and 32 grabs in 2014.

"You can't get any closer than we've already been," Torrey said of his chemistry with Flacco, per The Baltimore Sun. "I have folks tweeting me how terrible I am, and I could very easily have had three touchdowns and 300 yards the past couple weeks. That's how the ball rolls. I'm not used to it, but we'll get over it soon. We were as close as you can get to touchdowns. We just have to be on the same page and get it done."

Said Torrey: "It'll happen. It has no choice but to happen. The way we've been practicing, it has no choice but to happen. I can't say when. I hope it's Sunday, but it'll happen soon."

With the focus on Steve L Smith's revenge game against the Panthers, it would be a good time for Flacco to connect on one or two deep balls to Torrey Smith. We're not counting on it, but he's a better player than he's showed in the first three weeks and Dennis Pitta's absence may send a few extra targets his way.
