SANTA CLARA Fuming that Colin Kaepernick has killed your fantasy football team the past two weeks? Go ahead and send him an angry tweet. The 49ers quarterback uses them as motivation.
"It's something that I do for me," Kaepernick said Tuesday. "It helps me."
He keeps a close eye on his Twitter feed. In the hour before he spoke to reporters Tuesday, he marked as "favorites" seven additional insulting and critical messages. He seems to especially like/loathe the ones that include references to former 49ers quarterback Alex Smith.
12b @GAJICMAGIC: I've always said alex smith was better then you
Michael Yohannes @mikeyohannes95: one year wonder, the truth hurts bro
Ivan Rangel @iVanR1288: We Want Alex smith back!!
After passing for a career-high 412 yards in Week 1, Kaepernick has had his worst two games since taking over for Smith as the starting quarterback last year. He's completed fewer than half of his pass attempts in those games, has thrown four interceptions to zero touchdown passes and has lost two fumbles.
Coach Jim Harbaugh and offensive coordinator Greg Roman have said Kaepernick's routine has been unaffected by the downturn. He's still among the first to arrive each morning, and both men said his confidence has not been shaken.
"I think Colin's doing fine," Roman said. "He's coming in every day, he's working hard. And that hasn't changed."
Counterintuitively, Kaepernick said he has no reaction to recent media criticism because he tunes it out. "I'm working," he said. "It's not something I listen to."
After all, today's athletes get plenty of criticism from non-traditional sources.
No bad blood Running back Frank Gore, who reportedly yelled at Harbaugh toward the end of Sunday's loss to the Colts, said he has "no issues" with his coach.
"No, I'm cool with Harbaugh," Gore said. "That's not me."
Gore had 70 rushing yards at halftime but only three carries in the second half despite the close score. He said he's frustrated by the two-game losing streak because he said the offense is capable of being so much better.
"We've just got to get back to us, and being one," Gore said. "We'll be fine. We feel we can do whatever we want, like before."
Roster moves With cornerback Nnamdi Asomugha likely to miss Thursday's game because of a knee injury, the 49ers promoted practice-squad cornerback Darryl Morris to the 53-man roster and signed pass rusher D'Aundre Reed to the practice squad. The 49ers had an extra roster spot after placing Aldon Smith on the non-football injury list a day earlier.
Morris (5-foot-10, 188 pounds), who was undrafted out of Texas State last spring, is one of the fastest players on the squad.
Reed (6-4, 260) was a defensive lineman in Minnesota but projects to outside linebacker/pass-rush specialist with the 49ers. Reed, a seventh-round pick by the Vikings in 2011, was active for six games last season. He was part of the Vikings' final cuts last month and worked out for the 49ers on Monday. Reed was born in Sacramento and said he still has family in town.
Injuries Tight end Vernon Davis, who missed Sunday's game because of a hamstring strain, practiced on a limited basis. Linebacker Patrick Willis (groin) and Asomugha (knee) did not practice.
Defensive coordinator Vic Fangio would not rule Willis out against the Rams. "He's making a lot of progress," Fangio said. "It remains to be seen whether he'll be ready on Thursday or not."
