McKee (thumb) was a limited participant at practice Thursday.

McKee was limited for the second day in a row as he continues to recover from a fractured right thumb. If McKee can't go in Week 3, Sam Howell would operate as the top backup option behind Jalen Hurts at quarterback against the Rams.

Purdy (left shoulder/toe) officially was limited at Thursday's practice, Nick Wagoner of ESPN.com reports.

Purdy now has put together back-to-back capped sessions, after which he touched on his health Thursday. Calling his turf toe variant a day-to-day issue, he told Matt Barrows of The Athletic that he's "happy with the progress I've been making with my foot, my toe. ... [We] gotta see at game time how I feel." Whether Purdy retakes the reins of the offense from Mac Jones this Sunday versus the Cardinals remains to be seen, but the range of possibilities for him appear to be starter, backup or even emergency third quarterback.

Ewers (coach's decision) is inactive for Thursday night's clash with the Bills.

The quarterback will serve as the emergency option for the third week in a row to start the season, meaning he can only enter the contest if Tua Tagovailoa and Zach Wilson get injured, sick or ejected. Ewers was drafted in the seventh round by the Dolphins back in April.

Purdy said after Thursday's practice that his turf toe variant is a day-to-day concern, and he's "gotta see at game time how I feel" Sunday against the Cardinals, Matt Barrows of The Athletic reports.

Per David Lombardi of SFStandard.com, Purdy was able to throw among other activity for a second consecutive session Thursday, potentially paving the way for him to miss just one game as a result of the toe injury. Purdy's activity level will be revealed on the 49ers' second Week 3 practice report, but if he goes down as a limited participant again, he'll have one more chance to put himself in a position to be available this weekend. Mac Jones is in line to start Sunday if Purdy cannot.

Purdy (left shoulder/toe) participated in the media-access portion of Thursday's practice, Nick Wagoner of ESPN.com reports.

After sitting out the 49ers' Week 2 win at New Orleans due to a turf toe variant, Purdy logged a limited session Wednesday and appears as if he'll have a similar listing one day later. His activity level will become known later Thursday, but it remains to be seen if he has a chance to start Sunday against the Cardinals, or if San Francisco is seeing if he is an option to serve as the team's emergency third quarterback behind Mac Jones and Adrian Martinez.

The Saints signed Dekkers to the practice squad Thursday, Katherine Terrell of ESPN.com reports.

Dekkers was just cut from the practice squad Wednesday. The undrafted rookie has been bouncing on and off the practice squad through the first three weeks of the season.

Burrow is on track to undergo a procedure Friday to repair his Grade 3 turf toe, provided that swelling isn't an issue, Ian Rapoport of NFL Network reports.

Rapoport notes that it's possible that the procedure could get pushed back a few days, but once the surgery happens, the QB will face an estimated three-month recovery. That's a timetable that could allow for a late-season return for Burrow, but for the time being Jake Browning will fill in as Cincinnati's top signal-caller, with Brett Rypien set to serve as his backup and Mike White and Sean Clifford currently on the team's practice squad.

Purdy (left shoulder/toe) officially was a limited practice participant Wednesday, Matt Barrows of The Athletic reports.

Purdy fulfilled coach Kyle Shanahan's expectation for his activity level from earlier Wednesday, per Eric Branch of the San Francisco Chronicle. During the media-access portion of the session, Purdy was third in the QB rotation behind Mac Jones and Adrian Martinez, according to Cam Inman of The San Jose Mercury News, and he was seen making throws and also jogging on what has been described as a turf toe variant, per Branch. Purdy thus seemingly has a chance to return to action Sunday versus the Cardinals, but how he fares Thursday and Friday will be telling for his Week 3 availability. Mac Jones will continue to start as long as Purdy is sidelined.

McKee (thumb) was limited in practice Wednesday.

McKee was limited in practice last week but was inactive as the Eagles' QB3 behind Jalen Hurts and Sam Howell in last Sunday's win over the Chiefs. Once healthy, McKee has a chance to usurp Howell for QB2 duties.

The Saints released Dekkers from the practice squad Wednesday.

Dekkers was signed and cut by New Orleans multiple times over the offseason and has already bounced on and off the practice squad three times since the start of Week 1.
