from starter to backup after an injury for the second consecutive season. Despite losing five-straight this season and 1-8 as a starer Solomon Thomas jersey , coach Kyle Shanahan still hasn’t lost faith in the 49ers’ third-round pick.“C.J.’s story is not over and that’s what I want him to know,” Shanahan said to the media Thursday. “You’ve got to realize that the whole world will say, ‘This is what you are,’ and I’m not mad at the world for that. People watch sports and that’s what they think. But, C.J.’s story is not over and he has the ability, he has the toughness, he has the mind, to be a very successful quarterback in this league.”In 2017, Beathard suffered a knee injury late in the game against the Seattle Seahawks in Week 12, paving the way for Jimmy Garoppolo’s debut. The 49ers went on win five straight to close out the season with Garoppolo under center. Beathard didn’t see the starting lineup again until this season after Garoppolo’s Week 3 ACL tear against the Kansas City Chiefs.Beathard may be enduring a similar fate this season after a hand injury forced Nick Mullens into the spotlight against the Oakland Raiders. The once practice squad quarterback orchestrated one of the most successful quarterback debuts in NFL history, completing 16 of 22 passes (72%) for 262 yards, three touchdowns, no turnovers and a quarterback rating of 151.9. Shanahan named Mullens the starter going into the team’s Week 10 matchup against the New York Giants on Monday Night Football. Shanahan’s faith in Beathard stems from his time in Washington alongside now Minnesota Vikings quarterback Kirk Cousins, who was signed in the offseason to a three-year, fully-guaranteed $84 million contract“Kirk Cousins in his first nine games, do you know what his record was? 1-8. He had 19 picks and 18 touchdowns,” Shanahan said “C.J. is 1-8. I think he has 13 picks. It doesn’t mean that he’s him, but I also know that a lot of people gave up on Kirk because of how he started and everyone wanted to put it on one guy when it was a lot more than just that.”Beathard’s completed 57% of his passes for 12 touchdowns, 13 interceptions and a QB rating of 74.6 over his two years with the 49ers. Despite again being demoted, the former Iowa quarterback has been able to keep a positive mindset as he moves into an assistant role being Mullens.“It’s tough,” Beathard said, via ESPN’s Nick Wagoner. “I mean, it feels like two years in a row kind of going through it. But it’s something that’s going to make me stronger in the end, I feel like. I think God’s testing me and I think it’s all going to make me stronger in the end, make me a better person, make me a better quarterback Authentic Ahkello Witherspoon jersey , a better player in the long run.”“C.J.’s story is not over and he has the ability, he has the toughness, he has the mind, to be a very successful quarterback in this league,” Shanahan said. “Don’t let other people tell you it’s over because it hasn’t gone the way you wanted it.” The Kansas City Chiefs are on an upward trajectory, their blistering start spearheaded by a young, transcendent quarterback in Patrick Mahomes who is already setting NFL records.The San Francisco 49ers are the opposite in every way.Not only were they soundly beaten in a 38-27 loss at Arrowhead Stadium on Sunday, trailing at one point by four touchdowns, they also lost their own franchise quarterback when Jimmy Garoppolo was carted off in the closing minutes with what appears to be a season-ending knee injury.49ers coach Kyle Shanahan said the team will know more Monday, when Garoppolo has another round of tests in San Francisco. But he acknowledged late Sunday that the injury appears to be an ACL."Any time you lose your starting quarterback," Shanahan said, "that's a big deal."The 49ers (1-2) signed Garoppolo to a five-year, $137.5 million contract earlier this year after he led them to five consecutive wins to cap last season. And despite some turnover problems the first two weeks he had been pretty good, throwing a pair of touchdown passes against Kansas City.Everything turned in the fourth quarter, though, when Garoppolo scrambled toward the sideline. His left knee buckled as he cut back, rather than step safely out of bounds, and Chiefs cornerback Steven Nelson delivered a wicked shoulder-to-shoulder shot for good measure.C.J. Beathard wound up entering the game, threw a touchdown pass that was wiped out by offensive pass interference, and never got to take another snap as the Chiefs put the game away.His next snap will probably be the first one next week against the Chargers."It' definitely a blow. He's a great quarterback and obviously a great leader," said Beathard, who started five games last season before Garoppolo arrived in a trade with New England."Just keep these guys together. Keep leading them," he said. "We had a lot of injuries today, not just Jimmy. A lot of guys went down today. Just a matter of keeping everybody healthy next week."Meanwhile, the Chiefs (3-0) couldn't be happier with the performance of their young quarterback.Mahomes threw for 314 yards and three touchdowns against San Francisco, giving him 13 on the year without an interception. That broke Peyton Manning's NFL record for the first three weeks of a season.Perhaps most impressive Youth DeForest Buckner jersey , though, was the way Mahomes spread the wealth. He targeted 11 different receivers, connected with eight and found three with touchdown throws."Pat lives for these moments," said Chiefs wide receiver Chris Conley, who had one of the TDs. "I think he excels when the lights are on, and in front of big crowds. I think he's right at home. I think he's in his element. I think he's still growing into his role as the starting quarterback here, and we've just got to keep working with him and growing as well."As the 49ers and Chiefs roll into next week, here are five takeaways from Sunday:PENALTY PROBLEMS: The 49ers were whistled for 14 penalties for 147 yards, and that doesn't count a couple instances of off-setting flags and where they were penalized twice on the same play. That yardage total is substantial chunk of the 408 yards of total offense managed by San Francisco.SACK ATTACK: The Chiefs only had two sacks through the first two weeks, but Justin Houston had two by himself on Sunday. Dee Ford also had a sack before leaving with a groin injury, and Allen Bailey had another to help stop San Francisco's final drive of the game.RUN, RUN, RUN: San Francisco rallied on the legs of Matt Breida, who led the NFL in rushing coming into the game and had 90 yards on 10 carries, and Alfred Morris, who had 14 carries for 67 yards and a touchdown. With uncertainty at quarterback, the 49ers' ground game will be even more important.SPEAKING OF RUN: Chiefs running back Kareem Hunt, last year's rushing champ, had his first two TD runs this season. He only gained 44 yards on 18 carries against San Francisco, but many of them came in the closing minutes, when he picked up two first downs to put the game away.MORE INJURY NEWS: The 49ers lost cornerback Richard Sherman to a calf injury, safety Adrian Colbert to an ankle injury, linebacker Reuben Foster on a tackle and backup defensive back Tarvarius Moore to a wrist injury. Throw in a shoulder injury to safety Jaquiski Tartt that kept him on the inactive list and San Francisco has plenty of injury problems on defense.
