Daniels sustained a dislocated left elbow in the fourth quarter of Sunday's 38-14 loss to the Seahawks and will be sidelined indefinitely, though the Commanders aren't yet certain whether he'll miss the rest of the season, John Keim of ESPN.com reports.

EDGE Analysis

Though Washington was trailing by 31 points midway through the fourth quarter, Daniels remained in the game before suffering the gruesome injury to his non-throwing arm when he was sacked for the fourth time in the game at the Seahawks' four-yard line. His elbow bent backward on the tackle, and while head coach Dan Quinn didn't provide an immediate diagnosis for Daniels' injury following the game, early tests have apparently ruled out a fracture. The second-year quarterback is scheduled to undergo an MRI on Monday to confirm the diagnosis, after which a firmer timeline for his recovery should become clearer. At the very least, Daniels looks destined to miss the Commanders' Week 10 game versus the Lions, and a stint on injured reserve -- and a minimum four-game absence -- looms as a likely outcome. Marcus Mariota replaced Daniels late in Sunday's game and would once again be the next man up at quarterback for Washington, having already filled in when Daniels missed three games earlier this season due to knee and hamstring injuries.

Head coach Dan Quinn confirmed that Daniels suffered a left elbow injury in Sunday's 38-14 loss to the Seahawks, but Quinn didn't have any further updates on Daniels' status, Nicki Jhabvala of The Athletic reports.

EDGE Analysis

Daniels needed a brace to stabilize his left, non-throwing arm after sustaining an injury in the fourth quarter. A more concrete recovery timeline for Daniels will likely be established following additional evaluation of the injury. Marcus Mariota is set to fill in as the starting QB beginning with Week 10 against the Lions.

Daniels walked off the field with his left arm in a brace after sustaining an injury in the fourth quarter of Sunday's game against the Seahawks, Tom Pelissero of NFL Network reports.

EDGE Analysis

Daniels appeared to sustain a significant injury to his left arm at the end of a scramble with the Commanders trailing 38-7 in the fourth quarter. Marcus Mariota will finish out the game in relief, while further evaluation of Daniels' injury will be required before a return timetable is established. Prior to the injury, Daniels completed 16 of 22 passes for 153 yards, no touchdowns and one interception while rushing 10 times for 51 yards and a touchdown.

Daniels will start Sunday's game against the Seahawks,

EDGE Analysis

He returned to full practice participation Wednesday after missing the loss at Kansas City on Monday. Daniels made it through the week without any setbacks and will now return to the starting lineup, leading an offense that won't have WR Terry McLaurin (out - quadriceps) in Week 9.

Daniels (hamstring) practiced fully Wednesday.

EDGE Analysis

Coach Dan Quinn told Tashan Reed of The Washington Post earlier Wednesday that Daniels was slated for a full week of practice, and he ended up kicking it off with no restrictions whatsoever in the first session of Week 9 prep. Daniels thus appears as if he'll miss just one game due to the low-grade right hamstring strain that he sustained Week 7 at Dallas. Friday's injury report will unveil whether or not he enters the weekend with a designation ahead of Sunday's contest against the Seahawks.

Coach Dan Quinn said Wednesday that Daniels (hamstring) will have a full week of practice in advance of Sunday's game against the Seahawks, Tashan Reed of The Washington Post reports.

EDGE Analysis

Daniels sat out Monday's game at Kansas City due to a low-grade right hamstring strain that he suffered Week 7 at Dallas, allowing Marcus Mariota to get a third spot start of the campaign. On Tuesday, Quinn told JP Finlay of NBC Sports Washington that the Commanders "plan on him being a part" of the practice plan during Week 8 prep, but Quinn's comment one day later doesn't mean Daniels necessarily will be listed as a full participant all week. In the end, Wednesday's injury report will reveal whether or not Daniels was able to handle all on-field work.

Commanders head coach Dan Quinn said that Daniels (hamstring) had a good rehab session and will participate in Wednesday's practice, JP Finlay of NBC Sports Washington reports.

EDGE Analysis

Quinn didn't reveal whether Daniels will be a limited or full participant in Wednesday's session, but the Commanders anticipate the quarterback being on the field in some capacity for each of their three practices this week. If his injured right hamstring holds up well in on-field workouts, Daniels should be in line to start Sunday's game against the Seahawks. The second-year signal-caller missed Monday's 28-7 loss to the Chiefs due to the hamstring issue and previously sat out Weeks 3 and 4 while recovering from a sprained knee.

Daniels will test his injured hamstring in workouts on Sunday, and the Commanders think he has a chance to return in Week 9 against the Seahawks, Jay Glazer reported on Fox NFL Sunday.

EDGE Analysis

No matter how the testing unfolds, Daniels will still miss Monday night's game against the Chiefs, but he's made enough progress during the week to create some optimism for next week. Marcus Mariota will start on Monday night in Daniels' stead versus Kansas City.

NFL Network's Ian Rapoport reported Thursday that there's a "real possibility" Daniels misses just one start with his low-grade hamstring strain.

EDGE Analysis

Daniels has already been ruled out for Monday night's game against the Chiefs due to the hamstring injury he suffered in last Sunday's loss to the Cowboys, but it sounds like he's not looking at any sort of extended absence. Marcus Mariota will be under center against Kansas City, and Daniels would then be in line to return to the lineup in Week 9 at home against the Seahawks.

Coach Dan Quinn said Thursday that Daniels (hamstring) has been ruled out for Monday's game at Kansas City.

EDGE Analysis

Daniels missed most of the second half of this past Sunday's game at Dallas due to a hamstring injury, and after undergoing an MRI on Monday, it was revealed to be a low-grade strain of his right hamstring. As of Wednesday, he wasn't trending in the right direction to play Week 8, per Ian Rapoport of NFL Network, and Quinn confirmed as much one day later. The Commanders made the decision so that Daniels can focus only on rehab and treatment this week and that the issue isn't a long-term one, as Quinn told John Keim of ESPN.com. Marcus Mariota will make his third start of the season in place of Daniels on Monday.
