The Dolphins have released Sanu, according to Tom Pelissero of NFL Network.

EDGE Analysis

In eight games with the 49ers last season, Sanu caught 15 passes on 24 targets for 177 yards. The 33-year-old wideout now is an option for team's looking to add veteran depth ahead of Week 1.

Sanu signed a contract with the Dolphins on Tuesday, Adam Schefter of ESPN reports.

EDGE Analysis

Sanu turns 33 in August and hasn't reached 200 yards in a season since 2019. He was a functional third receiver for the 49ers before dealing with a knee injury last season, but he'll likely be lower on the depth chart in Miami so long as Tyreek Hill, Jaylen Waddle and Cedrick Wilson stay healthy.

Sanu (coach's decision) is listed as inactive for Sunday's NFC Championship at the Rams, Nick Wagoner of ESPN.com reports.

EDGE Analysis

Only four days removed from the 49ers activating him from injured reserve, Sanu will miss his 12th game in a row. It's unclear if his formerly injured knee is to blame, but the team's receiving corps is mostly healthy, so he'll remain in street clothes Sunday. Behind San Francisco's top duo of Deebo Samuel and Brandon Aiyuk, Jauan Jennings, Trent Sherfield and Travis Benjamin as the other wideouts available to the offense.

Sanu (knee) wasn't listed on the 49ers' injury report Wednesday, Eric Branch of the San Francisco Chronicle reports.

EDGE Analysis

Sidelined since Week 9 due to a knee sprain, Sanu was activated from injured reserve Wednesday and avoided the injury report entirely following his first official practice since being activated. While Deebo Samuel and Brandon Aiyuk occupy the top two spots on the team's depth chart at wide receiver, Sanu will contend with Jauan Jennings for any snaps that linger at the position in Sunday's NFC Championship Game at the Rams. In eight appearances this season, Sanu recorded 15 catches (on 24 targets) for 177 yards and no touchdowns.

The 49ers activated Sanu (knee) from injured reserve Wednesday, Cam Inman of The San Jose Mercury News reports.

EDGE Analysis

Sanu reached the end of his 21-day window for the 49ers to either activate him from IR or rule him out for the rest of the season. It's unclear if he'll be available for Sunday's NFC Championship Game against the Rams, and it's also uncertain what his role would be if he plays, given that Jauan Jennings has provided solid work as the No. 3 receiver. Sanu caught 15 of 24 targets for 177 yards in eight regular-season games, with his most recent appearance coming Week 9.

Sanu (knee) being activated from IR wasn't among the transactions made by the 49ers in advance of Saturday night's playoff game against the Packers.

EDGE Analysis

Until Sanu is activated, Deebo Samuel, Brandon Aiyuk, Jauan Jennings, Trent Sherfield, Travis Benjamin and River Cracraft profile as the 49ers' available wide receiver options.

Sanu (knee) being activated from injured reserve wasn't among the transactions made by the 49ers ahead of Sunday's wild-card game at Dallas.

EDGE Analysis

Sanu thus won't be eligible to return to the active roster until the divisional round, at the earliest, but the 49ers first will need to secure a victory in their playoff opener. The team opened his practice window on Jan. 5, so there's plenty of time for the 10th-year pro to prove his knee is healthy. With Sanu still sidelined, though, Deebo Samuel, Brandon Aiyuk, Jauan Jennings, Trent Sherfield, Travis Benjamin and perhaps River Cracraft will serve as San Francisco's options at wide receiver Sunday.

Sanu (knee) wasn't among the players added to San Francisco's roster Saturday ahead of Sunday's regular-season finale against the Rams, Cam Inman of The San Jose Mercury News reports.

EDGE Analysis

San Francisco first designated Sanu for return from injured reserve Wednesday, so the team will have the opportunity activate him at some point in the next two and a half weeks, if the 49ers remain alive in the playoffs at that point. Before spraining his knee Week 9 against the Cardinals and landing on IR, Sanu appeared in eight games and recorded 15 receptions for 177 yards on 24 targets.

The 49ers designated Sanu (knee) for return from injured reserve Wednesday.

EDGE Analysis

Sanu has missed eight games in a row due to a sprained knee sustained Week 9 against the Cardinals. With his practice window now open, he'll have a trio of chances this week to prove his health ahead of Sunday's season finale at the Rams. Even if he's activated for Week 18, Sanu would be competing with Jauan Jennings and Trent Sherfield for snaps and targets behind the 49ers' top two wide receivers Deebo Samuel and Brandon Aiyuk.

The 49ers placed Sanu (knee) on injured reserve Monday.

EDGE Analysis

San Francisco already had ruled Sanu out in advance of Monday's game against the Rams, and the 49ers evidently didn't have much confidence he'll make a full recovery from a sprained knee within the next two weeks, either. With Sanu now officially out until at least Week 13, Trent Sherfield and Jauan Jennings are the leading candidates to vie for the No. 3 wideout job behind starters Deebo Samuel and Brandon Aiyuk.
