SANTA CLARA David Montgomery Jersey , Calif. (AP) — McKinnon will miss a second straight season after having complications in his recovery from a knee injury.McKinnon was placed on season-ending injured reserve on Saturday as the 49ers cut their roster down to the 53-player limit.McKinnon was one of the team’s major acquisitions in free agency in 2018, signing a four-year, $30 million contract but he has yet to play a game for San Francisco because of injuries.General manager John Lynch said the team decided it was better to shut McKinnon down for the entire season rather than keep him on the initial roster and placing him on injured reserve with the option to return after at least eight weeks.“We sought a lot of opinions on this,” Lynch said. “Ultimately the decision was made that he needs to undergo another procedure and being ready in eight weeks wasn’t going to be an option. That decision was made for us. We’re hopeful for Jerick that this one is successful and we believe it will be.”McKinnon tore his right ACL a week before the start of last season and was unable to fully recover this year. He started training camp on the physically unable to perform list after having a setback in mid-July. He was activated on Aug. 6 and went through two light practices before being shut down for three weeks. He came back again this week only to have another setback.The 49ers have depth at running back with free-agent acquisition Tevin Coleman having the most playing experience over his career. He has been a key part of Atlanta’s offense the past few years and figures to share the duties with big-play threat Matt Breida.Special teams standout Raheem Mostert also made the roster and has shown he can contribute at running back when needed.The Niners cut Jeff Wilson Jr. despite him running for four TDs the past three games and 100 yards in the exhibition finale.In other roster cut-down news, the Niners cut 2016 first-round offensive lineman Joshua Garnett and kept three quarterbacks with Nick Mullens and C.J. Beathard both on the roster as backups to Jimmy Garoppolo.Lynch said they had offers to move one of the quarterbacks but opted to carry three on the initial roster for the first time in three seasons under coach Kyle Shanahan.“You set a price and you stand firm on it,” Lynch said. “While we had discussions, we never deviated on what that price was and no one met it. We were happy to carry three.”The other players cut by San Francisco on Saturday were defensive backs Antone Exum Jr., Marcel Harris and Tyree Robinson; linebackers Demetrius Flannigan-Fowles, Elijah Lee, David Mayo and LaRoy Reynolds; defensive linemen Jamell Garcia-Williams, Kevin Givens http://www.bearscheapstores.com/riley-ridley-jersey-cheap , Damontre Moore, Jordan Thompson and Jeremiah Valoaga; receivers Malik Henry, Jordan Matthews and Chris Thompson; offensive linemen Ross Reynolds and Najee Toran; tight end Daniel Helm, quarterback Wilton Speight and running back Austin Walter.San Francisco kept injured defensive lineman Kentavius Street (knee) on the roster, but will move him to IR this week to make room for another healthy player with a fourth safety a likely possibility.The Niners also waived safety Adrian Colbert and offensive lineman Andrew Lauderdale with injury designations, placed receiver Nick Williams on IR, moved tight end Garret Celek to the physically unable to perform list and long snapper Kyle Nelson to the suspended list. SANTA CLARA, Calif. (AP) — The Broncos looked beleaguered, beat up and undermanned against the lowly San Francisco 49ers.Overmatched, too? You bet.Short-handed they were, and it sure showed. Yet on this day http://www.cowboyscheapauthenticstore.com/trysten-hill-jersey-cheap , George Kittle might have been too much even if Denver had been at full strength.Case Keenum got going too late in a 20-14 loss to San Francisco on Sunday, four days after top target Emmanuel Sanders went down with a torn left Achilles tendon in practice Wednesday.The Broncos (6-7) were out of sorts early, then trying to play catch-up from a 20-0 deficit that saw Kittle take apart the defense time and again on the way to an 85-yard touchdown catch, 210 yards receiving and becoming the 49ers’ first tight end to reach 1,000 yards receiving.“Simply, we didn’t play well, no excuses. We can’t point fingers,” coach Vance Joseph said. “That team came out and outplayed us, in the first half especially. Our record right now, we’re still in it. Every game now is a must win. We haven’t talked about that, but we have to now. Every game that we play from now on is a must win.”Phillip Lindsay ran for a 3-yard score in the third then Keenum connected with DaeSean Hamilton on a 1-yard touchdown toss with 3:53 remaining. Keenum went 24 of 42 for 186 yards.He surely missed Sanders Connor McGovern Jersey , who led the team with 71 catches for 868 yards and four touchdowns in a bounce-back year. His injury came three days after star cornerback Chris Harris Jr. broke his leg, leaving the Broncos without seven starters from their season opener.“It’s tough,” Keenum said. “They’re guys you can’t replace.”Tim Patrick and Hamilton had seven receptions apiece, Patrick finishing with 85 yards receiving and Hamilton with 47, but most of their production came in the second half playing from way behind.“We got off to a slow start and then we picked it up in the second half,” Patrick said. “We just had to get it going. It was the first time as an offense all together in there. We were kind of shaky in the beginning, but once we got it clicking it was hard to stop us.”Meanwhile, Kittle couldn’t be slowed down in the first half, when he had all seven of his catches and 210 yards. He was only targeted once after halftime.After the game, Joseph reiterated how the Broncos must not beat themselves by falling way behind and making it harder.Denver had two defensive holding penalties in a four-play span in the first quarter and 11 total penalties for 62 yards.“We just have to be consistent,” nose tackle Shelby Harris said. “We can’t go out in the first half and go down 20-0.”There were a few defensive highlights.Von Miller sacked Nick Mullens for a 9-yard loss late in the second quarter. Including the postseason Khari Willis Jersey , Miller’s 103½ sacks matched the franchise record held by Simon Fletcher.Linebacker Bradley Chubb had two more sacks for 12 on the season to break Miller’s franchise rookie record of 11½ set in 2011.Miller was angry about his own miscues.“I had three false starts, and that’s ridiculous,” he said. “I’m a gambling man, and I broke today. I didn’t play like I’m supposed to today.”Most of the Broncos will be echoing those sentiments.“Now, it’s back to the lab,” Miller said.
