Follow along right here throughout the contest for a running diary of today's game.
Garrett Celek (hip) and Jimmie Ward (quad) are San Francisco's two most notable inactives. Garrett Celek will start in place of McDonald. Either Rashard Robinson or Keith Reaser will get the nod for Ward. Both cornerbacks should see plenty of playing time. Backup tight end could also see increaed snaps in McDonald's absence.
The Cowboys will be without a number of starters on Sunday. Left guard La'el Collins (toe), left tackle Tyron Smith (back), top cornerback Orlando Scandrick (hamstring) and top wideout Dez Bryant (knee) are all out against the 49ers.
Here's the 49ers full list of inactives: McDonald, Ward, Christian Ponder, Keshawn Martin, Tony Jerod-Eddie, Taylor Hart and John Theus.
And the Cowboys: Collins, Bryant, Scandrick, Smith, Darius Jackson, Mark Nzeocha and Tony Romo.
Dallas got the ball to open the game. Robinson came out with the 49ers first-team defense, and the rookie corner made two early tackles.
Ezekiel Elliott carried the ball twice for 11 yards, Dak Prescott added a 9-yard run and a third-down completion to Cole Beasley moved the Cowboys into 49ers territory. A false start penalty and clutch third-down tackle by Antoince Bethea stalled the Dallas drive at San Francisco's 29-yard line. Dan Bailey missed the ensuing 47-yard field-goal attempt to keep the game scoreless.
Blaine Gabbert used his legs to convert San Francisco's first third-down attempt on a 7-yard keeper towards the left sideline. The quarterback then connected with Quinton Patton for 13 yards on 3rd-and-12.
Three plays later, Gabbert hit a wide open Jeremy Kerley for a 33-yard touchdown to put the 49ers on top, 7-0. (6:41)
San Francisco went 3-for-3 on third down on the scoring drive. Kerley found space in the middle of the field and then made a man miss on his way into the end zone.
One first down is all Dallas would get on their following drive. On 3rd-and-4, NaVorro Bowman came in untouched on a blitz and sacked Prescott to force a Dallas punt.
Gabbert continued to roll on the 49ers second possession. Completions of 13 yards to Garrett Celek, 25 yards to Celek and 17 yards to Kerley moved San Francisco to the Cowboys 12-yard line as the first quarter came to a close.
The 49ers finished the opening quarter 5-for-5 on third down.
Gabbert kept the ball for seven yards on the first play of the second quarter. Hyde followed with a 3-yard carry to set up 3rd-and-1.
Hyde did the rest from there, finding the end zone from 3-yards out to put the 49ers up 14-0 (13:55).
Trent Brown delived a perfect block to seal the right edge on the score. Hyde has been flexing plenty this season and now leads the league with five touchdown runs.
San Francisco forced another stop against Dallas' offense. On 3rd-and-3, Robinson broke up a pass intended for Brice Butler which led to another Cowboys punt.
A 1-yard run from Hyde made the 49ers 7-for-7 on third down to start the game. The possession, however, would stall, and Bradley Pinion punted it back to Dallas.
The 49ers defense appeared to have another stop, but a curious personal foul helped lead to the Cowboys first points of the game. Chris Davis and Ronald Blair III were trying to bring down a scrambling Prescott when Jaquiski Tartt came in to help push the quarterback to the ground. Although Prescott wasn't down and the whistle hadn't blown, Tartt was flagged for a dead-ball personal foul. Davis and Blair were credited with a .5 sack each, the first of their respective careers.
Three plays later, Prescott hit Terrance Williams for a 20-yard touchdown to put Dallas on the scoreboard, 14-7. (2:58)
The points were the first allowed by the 49ers at home this season. San Francisco had previously outscored opponents 42-0.
Dallas would march down the field before halftime and tie the ball game. Prescott nickled-and-dimed the 49ers down the field with three completions to Jason Witten. A 10-yard completion to Williams got the Cowboys inside the 10-yard line.
On 1st-and-goal from the 49ers 4-yard line, Prescott found Butler in the end zone to tie the game at 14-14. (0:12)
San Francisco took one knee and the teams went in for halftime. The 49ers will get the ball to start the third quarter.
Hyde opened the quarter with a 32-yard run. Gabbert followed with a beautiful throw to Celek down the right sideline for a gain of 29 yards. The tight end made a ridiculous one-handed catch but was slow to get up after being tackled.
The drive stalled and Phil Dawson drilled a 36-yard field goal to give the 49ers the lead, 17-14. (12:18)
Dawson's field goal gives him 390 for his career.
The team's then traded stops.
Midway through the third quarter, Bowman was forced to leave the game with an apparent leg injury. The linebacker walked off under his own power, but had a considerable limp. It's a scary situation for the 49ers who cannot afford to lose their best defender.
Elliott busted loose for 23 yards to get the Cowboys to midfield. Prescott to Butler for 14 yards converted a 3rd-and-5 situation. Elliott broke free again, this time for 17 yards to get near the goal line.
The Cowboys rookie ball-carrier finished what he started, scoring from 1-yard out to give Dallas a 21-17 lead. (1:08)
Elliott eclipsed the century mark and now has 103 rushing yards and his third touchdown of the season.
The 49ers made it near midfield but Gabbert's third-down pass to Kerley was broken up to force another punt.
An unsportsmanlike conduct penalty against the Cowboys helped San Francisco get a much needed stop. Robinson broke up Prescott's third-down pass intended for Butler to bring out Dallas' punt team. Kerley followed with a 26-yard punt return to get the 49ers near midfield.
Gabbert tried for a deep ball to Torrey Smith but was intercepted by Morris Claiborne. Smith had Claiborne beat but the ball was underthrown.
Elliott ripped off 26-yards as the Cowboys got rolling immediately. Robinson's third pass breakup of the game, this one coming on a third-down throw into the end zone, kept the 49ers in the game.
Bailey's field goal was good from 22-yards out to extend Dallas' lead to 24-17. (4:11)
Robinson's clutch play ensured San Francisco got the ball back within one score.
Gabbert opened the ensuing drive with completions of 9-yard to Celek, 7-yards to Kerley and 20-yards to Kerley.
The 49ers ultimately failed to convert on 4th-and-6 whe Gabbert's pass to Smith came up short of the first-down marker.
Things went from bad to worse for San Francisco. First-round pick DeForest Buckner went down with a leg injury on the Cowboys final drive.
Dallas closed out the 24-17 win to improve to 3-1 on the season. San Francisco dropped to 1-3 on the year and play again on Thursday at home against the Arizona Cardinals.
