Juszczyk returned to Sunday's game against the Saints after being evaluated for a concussion, Jennifer Lee Chan of NBC Sports Bay Area reports.

EDGE Analysis

After getting dinged up in the fourth quarter, the 28-year-old fullback was deemed fine after further evaluation. Juszczyk will continue to pave the way for the 49ers' running backs while occasionally contributing in the passing game.

Juszczyk left Sunday's game against the Saints and is being evaluated for a concussion, Eric Branch of the San Francisco Chronicle reports.

EDGE Analysis

Juszczyk suffered the injury on a hit directly to the head after he caught a pass in the fourth quarter, and was visibly shaken up. He'll enter the league's mandated concussion protocol, and we'll need to be cleared by an independent neurologist before returning.

Juszczyk had seven catches for 63 yards in Sunday's 36-26 win over Arizona.

EDGE Analysis

Juszczyk set new season highs in receptions, yards and targets in one fell swoop. The versatile fullback was targeted just nine times over his previous five healthy contests, which was a bit surprising given the lack of receiving talent that San Francisco brings to the table. Juice had stretches of flirting with deep-league value (even as a fullback) over his first two seasons in San Francisco, so maybe this strong outing will earn the 28-year-old more looks down the stretch.

Juszczyk was unable to haul in his lone target of Monday's 27-24 loss to Seattle.

EDGE Analysis

Juszczyk didn't earn a touch in his Monday return from a knee injury, but he did make a difference early, sealing off a block to help spring Tevin Coleman for a 22-yard gain midway through the first quarter. Juszczyk has been a solid enough receiver out of the backfield in recent seasons to warrant potential consideration on bye-heavy weeks, but an injury-plagued 2019 has held him to just seven total touches for 82 yards this season. Next up is Arizona's 31st-ranked total defense.

Juszczyk (knee) does not carry an injury designation into Monday's prime-time contest against the Seahawks, Nick Wagoner of ESPN.com reports.

EDGE Analysis

Juszczyk's status is surprisingly critical, as the 49ers are expected to be without their star tight end, George Kittle (knee/ankle), heading into the pivotal contest. The All-Pro fullback was mentioned by head coach Kyle Shanahan as a potential fill-in for Kittle, suggesting the respective players' roles aren't much different than the other, although Juszczyk's running back designation won't necessarily help fantasy owners hoping to replace the productive tight end.

Juszczyk (knee) was participating in Tuesday's practice, Matt Barrows of The Athletic reports.

EDGE Analysis

Juszczyk's level of participation remains unclear since the 49ers won't have an official injury report until Thursday, but it's nonetheless a good sign about his potential return. The 28-year-old was given a four- to six-week recovery timeline after suffering an MCL sprain Oct. 7, and Monday's game against the Seahawks would be the five-week mark. In fact, Jusczyk told David Lombardi of The Athletic he feels "100 percent" and is on track to play Monday.

Juszczyk (knee) began running again Wednesday and said he may be able to return in "another week or two," Nick Wagoner of ESPN.com reports.

EDGE Analysis

Juszcyk was given a 4-to-6 week timeline after suffering the MCL sprain Oct. 7, so a return in two weeks would put him directly on track with that timeline. The 28-year-old has yet to resume practicing and is unlikely to return prior to the Nov. 11 game against the Seahawks, since the 49ers play on Thursday next week.

The 49ers announced Tuesday that Juszczyk (knee) will likely be sidelined for 4-to-6 weeks, Jennifer Lee Chan of NBC Sports Bay Area reports.

EDGE Analysis

After exiting Monday's 31-3 win over the Browns, Juszczyk was sent in for an MRI on Tuesday that confirmed the versatile fullback had sprained the MCL in his left knee. The loss of the 28-year-old for at least the next four games will deprive Jimmy Garoppolo of one of his favorite dump-off targets, while also leaving a potent San Francisco ground attack without a lead blocker. The 49ers could sign another fullback to compensate for Juszczyk's absence or have backup tight end Levine Toilolo -- a blocking specialist -- line up out of the backfield more frequently.

Juszczyk (knee) is believed to have suffered a sprained left MCL in Monday's 31-3 win over the Browns, Tom Pelissero of NFL Network reports.

EDGE Analysis

The 49ers will send Juszczyk in for an MRI later Tuesday before offering further clarity on his injury, but if the initial diagnosis proves accurate, he'll have a tough time making it back for the team's Week 6 matchup with the Rams. Juszczyk has only tallied 82 total yards on seven touches through four games, but his skills as a lead blocker have helped spark the 49ers' productive ground game this season.

Juszczyk appears to have suffered a left knee sprain, but the severity is still unknown, according to head coach Kyle Shanahan, Nick Wagoner of ESPN reports.

EDGE Analysis

Juszczyk will undergo an MRI on Tuesday, which will bring more clarity to the situation, but there's a good chance the Pro Bowl fullback could be sidelined for at least one contest. Look for more details to emerge when the team releases their practice report later this week.
