SANTA CLARA https://www.49ersfanshop.com/Garrett-Celek-Jersey , Calif. (AP) —o dwell on a heartbreaking loss to Aaron Rodgers and the Green Bay Packers.The Niners have to immediately shift their focus to another tough test with the undefeated Los Angeles Rams coming to town on Sunday.Coach Kyle Shanahan spent Tuesday morning going over the details of the previous night’s 33-30 loss to the Packers that featured Rodgers throwing the game-tying touchdown pass with 1:55 to play and then leading the game-winning field goal drive after an interception by C.J. Beathard.Then it was quickly on to the Rams (6-0), the NFL’s only remaining unbeaten team, who will take on the 49ers (1-5) in just five days.“Short weeks are always tough, but sometimes it can be a good thing,” Shanahan said. “Last night was a heartbreaking loss. Our guys came out and I thought played extremely aggressive, very confident and gave it their all. Whenever you do that, it gave us a chance to win that game and we came up short. That’s tough. The guys put a lot into it and that’s hard. You get back here and it hurts a little bit today, but the good thing is, you’ve got to move on faster. There’s no time to sit here and sulk.”The Niners had their chances to earn their first win in three games since losing starting quarterback Jimmy Garoppolo to a season-ending knee injury on Sept. 23.Beathard threw two TD passes in the first half in his best performance of the season to help the Niners build a 24-20 lead. Raheem Mostert provided a boost to a running game that gained 174 yards. The defense limited Rodgers to two field goals during a seven-drive stretch starting in the second quarter.But it wasn’t enough. Rodgers picked on backup cornerback Greg Mabin to lead the tying TD drive capped by a 16-yard pass to Davante Adams.The 49ers then took over at their 47 with 1:49 to go after a personal foul on the kickoff return. Needing just 20 yards to get into field-goal range, Beathard completed a 7-yard pass to George Kittle on first down, had a pass batted down at the line on second down and then took a deep shot against the blitz on third down that turned into the interception by Kevin King.By not running the ball on second or third down Arik Armstead Jersey , the Niners gave Rodgers 1:07 to drive for the winning field goal and he delivered.“If I were to have it back, yeah, I’d love to call something that worked,” Shanahan said. “But, then when you get into third-and-3 versus an all-out blitz, there’s not many runs for that. That was the play that we didn’t make right there and that’s what happened. But, you’re always concerned about giving it back to Aaron. I thought we had a chance to win the game right there. I know our defense struggled in the first half definitely. I was happy with how they rebounded in the second half and they gave us a chance on offense to put them away. I thought that was our biggest opportunity right there and we came up short.”The 49ers made a roster move Tuesday, signing Tom Savage to a one-year deal to be the team’s No. 3 quarterback.San Francisco has been looking for help at quarterback ever since Garoppolo went down with his injury last month. Beathard was promoted to starter and Nick Mullens was elevated from the practice squad to be the backup.Savage was originally drafted by Houston in the fourth round in 2014. Savage played 13 games with nine starts in four seasons with the Texans. He completed 181 of 315 attempts for 2,000 yards, five touchdowns and seven interceptions. He spent training camp with New Orleans before being cut Sept. 1.“There’s one thing I always liked about Savage, from coming out of college. He’s got a strong arm. He’s a very tough player. He hangs in that pocket and plays the position well Frank Gore Color Rush Jersey ,” Shanahan said. “I was a fan of his coming out of college. He’s gotten to play in a number of NFL games so he’s been battle-tested. He was in a tough situation in Houston that didn’t work out for him, but I got to study him this preseason when he was in New Orleans and they have some similarities in their offense as ours.”NOTES: CB K’Waun Williams (shoulder), CB Ahkello Witherspoon (concussion) and CB Jimmie Ward (hamstring) are all day to day. … The 49ers waived TE Cole Wick to make room on the 53-man roster for Savage. … OL Zack Golditch was released from the practice squad. SANTA CLARA, Calif. (AP) — San Francisco 49ers free safety Adrian Colbert likely will miss the rest of the season with a high ankle sprain he suffered Sunday.The 49ers placed Colbert on injured reserve Monday and signed quarterback Tom Savage to a one-year contract to take his roster spot.Coach Kyle Shanahan estimated Colbert would be sidelined for six to eight weeks. He would be eligible to come off IR for the 49ers' second-to-last game, at home against the Chicago Bears on Dec. 23. But Shanahan talked as if Colbert, a second-year player out of Miami, will be shut down for the season. Rookie D.J. Reed will get the first opportunity to start at free safety in his absence."It's tough. It's part of football, though," Shanahan said. "It's not the first time that's happened. Colbert is one of those guys who got his opportunity last year because a lot of guys went down."The 28-year-old Savage, who made nine starts over three seasons with the Houston Texans, originally signed with San Francisco last Tuesday. He was waived Saturday when the 49ers promoted defensive back Tyvis Powell from the practice squad for Sunday's game against the Rams because of injuries in the secondary.But Savage was quickly re-signed to provide San Francisco with a third quarterback alongside starter C.J. Beathard and backup Nick Mullens. The 49ers lost Jimmy Garoppolo in Week 3 to a torn ACL.Shanahan remained firmly committed to Beathard on Monday despite a shaky performance in Sunday's 39-10 loss to the Rams.Beathard threw two interceptions and lost a fumble https://www.49ersfanshop.com/Bradley-Pinion-Jersey , giving him seven interceptions and three lost fumbles in five games (four starts). San Francisco (1-6) is winless since Beathard took over for Garoppolo."We've had 18 turnovers this year," Shanahan said. "I've watched every single one, definitely more than once. I recommend you guys (the media) do it too. You guys will see there's a lot of people involved in each one."The 49ers have an NFL-worst minus-15 turnover ratio, and the offense is only half the problem. San Francisco has forced just three turnovers — one interception and two fumbles — in seven games.Colbert is one of a few second-year defensive players — linebacker Reuben Foster and cornerback Ahkello Witherspoon are others — who haven't made the impact that was anticipated after their promising rookie seasons.Addressing his group of second-year defenders as a whole, Shanahan said: "Those guys worked extremely hard in the offseason. They came in ready to take it to another level and they haven't done that so far. That stuff's hard."Shanahan praised Colbert, however, saying the free safety was enjoying a strong game Sunday before hurting his ankle while trying to intercept interception on a deep pass in the third quarter.NOTES: Running back Matt Breida is day-to-day after tweaking his left ankle Sunday, but "his strength is good," Shanahan said. … Receivers Marquise Goodwin (ankle) and Pierre Garcon (knee) and strong safety Jaquiski Tartt (stinger) will be evaluated Wednesday. … Foster (shoulder) is expected to practice Wednesday.
