Davis (back) didn't take part in practice Wednesday, the Sacramento Bee reports.

Davis relayed after drills that he's able to move about better than he did Sunday, when he suffered his current back injury. However, the back spasms haven't subsided entirely, spurring the tight end to term himself "day-to-day," according to Matt Maiocco of CSN Bay Area. The 49ers' current picture at tight end is clouded, with Vance McDonald dealing with a knee concern, meaning interested parties should keep a close eye on the situation as the week continues.

Davis stated Wednesday that he's "day-to-day" due to his bout with back spasms, Matt Maiocco of CSN Bay Area reports.

Davis' activity level at Wednesday's practice hasn't been revealed, but he appears to be of the belief that he'll be OK. Because Vance McDonald (ankle) is similarly questionable, Derek Carrier represents the sole healthy tight end on the 49ers' roster. Expect the situation surrounding the position to clear up by week's end.

Davis said after Sunday's game that he is dealing with back spasms but expects to be okay, Bay Area News Group's Cam Inman reports. "I'll be alright," Davis said. "I'm not worried about it"

Davis did not return to Sunday's game against the Eagles after taking a hard hit to the back during the third quarter. It sounds as if he expects to play next Sunday versus the Chiefs, but fantasy owners will still want to keep a close eye on the situation, given that Davis entered Sunday as a game-time decision because of knee and ankle injuries that caused him to miss Week 3. Next in line for tight end snaps are Vance McDonald (ankle) and Derek Carrier, the first of whom was unable to play Sunday against the Eagles.

X-rays on Davis' back were negative, and the tight end said that he will be okay, CSN Bay Area's Matt Maiocco reports.

Davis did not return to Sunday's game against the Eagles after leaving in the third quarter. The injury could just be a bad bruise, but he was already dealing with ankle and knee issues, which made him a game-time decision Sunday. If Davis can't go next week versus the Chiefs, either Derek Carrier or Vance McDonald (knee) will get the start. McDonald was inactive against the Eagles, after being listed as questionable on the final injury report.

Davis returns to the 49ers' lineup (unlike fellow TE Vance McDonald) after a one-game absence and should be in line to see his share of looks in the team's Week 4 game plan, assuming no in-game injury setbacks.

NFL Network's Ian Rapoport indicates that Davis (ankle) is expected to suit up Sunday against the Eagles, NFL.com reports.

Davis' status is nonetheless worth verifying in advance of Sunday's 4:25 ET kickoff, but it appears as though the tight end should be able to give it a go in Week 4, barring any setbacks in pre-game warmups.

Davis (ankle) is a game-time decision for Sunday's game against Philadelphia after logging a limited practice Friday.

Davis disclosed that he was originally given a prognosis of 2.5 weeks for his injury, and Sunday will mark roughly the two-week mark. Unfortunately for Davis' owners, the 49ers don't play until 4:25 eastern time Sunday. Davis' top backup is Vance McDonald, who said he expects to play through his knee injury Sunday.

Davis (ankle) was limited in Wednesday's practice, the Sacramento Bee reports.

Davis is a step ahead of fellow tight end Vance McDonald (knee), who remained out of practice Wednesday. Moreover, Davis' activity level substantiates coach Jim Harbaugh's optimism that Davis will be available Sunday against the Eagles. If Davis achieves active status in Week 4, he'll look to build upon the nine targets that he earned in two appearances this season.

Davis (ankle) practiced Wednesday, the San Jose Mercury News reports.

Davis' level of participation has yet to be clarified, but he is clearly in a better spot to potentially return this week against the Eagles on Sunday than backup TE Vance McDonald, who still hasn't been cleared to return to practice.

Coach Jim Harbaugh is "optimistic, very hopeful" that Davis (ankle) will return to action Sunday against the Eagles, the San Jose Mercury News reports.

Both Davis and Vance McDonald sat out this past Sunday's game against the Cardinals, but Harbaugh's comments Monday suggest that Davis' absence could well be be limited to just one game. In any case, we'll track the tight end's practice participation in the advance of Week 4's 4:25 ET kickoff.

Davis (ankle) and Vance McDonald are both inactive for Sunday's game against the Cardinals.

As a result, Derek Carrier will start at tight end for the 49ers on Sunday and merits a look by those scrambling to replace Davis this week.

Davis (ankle) is doubtful to take the field Sunday at Arizona, NFL.com reports.

Although Davis was deemed a game-time decision on the final injury report of the week, he now seems all but certain to reside on the sideline in Week 3. On the other hand, Matt Maiocco of CSN Bay Area speculated Saturday that Davis was instead questionable to play Sunday, leaving a sliver of doubt about his availability. Owners may want to take a prudent approach and explore other tight end options, but his status should nevertheless be confirmed prior to the 49ers' 4:05 PM ET kickoff.

Davis (ankle/knee) did not practice Friday and is listed as questionable for Sunday's game against Arizona, CSN Bay Area reports.

Davis didn't practice at all this week, making him look like a highly questionable game-time decision for Sunday's game against Arizona. The 49ers have a 3:05 eastern time kickoff, which isn't ideal for his fantasy owners. Vance McDonald (knee) is also questionable, so it's not even clear who the backup would be if Davis needs to sit out.

Davis (knee/ankle) did not practice Thursday, CSN Bay Area reports.

According to CSN Bay Area's Matt Maiocco, Davis shed his crutches Thursday, but was still seen hobbling around in pain. While the absence of a sprain may allow the star tight end to suit up, he'll likely need the pain to subside within the next few days. Davis will likely be listed as either questionable or doubtful come Friday afternoon.

Davis (ankle/knee) didn't partake in Wednesday's practice, the 49ers' official site reports.

Davis was on crutches during drills, but because he emerged from Sunday's loss to the Bears with merely a deep bruise in his left ankle, there's a possibility that he takes the field in Week 3 at Arizona. With no sprain to speak of, owners should watch his status with interest as the week continues onward.

Davis' (ankle) MRI on Monday revealed only a deep bruise and no structural damage to his left ankle, making it possible that he plays Sunday against the Cardinals, CSN Bay Area reports.

Davis appears to have eluded a significant ankle injury, which could allow him to avoid missing any games. The tight end left Sunday night's game after getting his foot caught under an opponent and did not return following the incident. While Davis was seen using crutches after the game, he fortunately is only dealing with a bone bruise. At the moment, it's unclear if Davis will practice this week, making his status one to monitor on a day-to-day basis.

Davis is slated to undergo an MRI on his left ankle, Matt Maiocco of CSNBayArea.com reports.

Davis' Week 3 status is uncertain at this stage, especially given that he was spotted on crutches after Sunday's loss to the Bears. With No. 2 TE Vance McDonald dealing with a right knee injury, Derek Carrier currently slots in as the team's healthiest option at the position.

Davis (ankle) was seen on crutches after Sunday's game, ESPN.com's Paul Gutierrez reports.

Davis left Sunday's game in the fourth quarter after his ankle got trapped under Bears linebacker Jon Bostic. The most likely diagnosis is a sprained ankle, but said injury still leaves a wide range of possibilities. Fantasy owners will hope that this isn't the dreaded high-ankle sprain, and while the crutches aren't a good sign, they also aren't cause to panic. If Davis misses time beyond Sunday, Vance McDonald and Derek Carrier will take on increased roles in the offense, with McDonald the more intriguing fantasy option.
