While most San Francisco 49ers will get away during their bye week, running back Frank Gore plans on a stay-cation at the team’s facility. He won’t be alone: He has wide receiver Michael Crabtree to break in.

“Me and Crabtree are going to get it done,” Gore said Tuesday.
The 49ers hope to have Gore (ankle) and the newly signed Crabtree back when their season resumes Oct. 25 at Houston. That’s good, because the 49ers could use the help — from Gore, from Crabtree, from anywhere.
They rank 29th in the league in total yards, 31st in first downs per game and 27th in third-down efficiency. The offense was so horrid Sunday against the Atlanta Falcons that coach Mike Singletary indicated changes are in store along the offensive line. Right guard Chilo Rachal, for example, could be out of a starting job after back-to-back poor games.
The 49ers clearly need more firepower if they are to have any chance of keeping up with the league’s elite. Teams with a 300-yard passer this season are a combined 23-8 (.742). Those 23 wins by a 300-yard passer are the most in NFL history through the first five weeks.
The 49ers, in contrast, haven’t so much as topped 200 passing yards since the season opener (209 against Arizona).
Gore insisted Tuesday that everything will be fine, even along the offensive line. He returned to practice on a limited basis and said the ankle and foot injuries he sustained at Minnesota on Sept. 27 are just about healed.
Gore has rushed for 1,000 yards for three consecutive seasons. He said he retains faith in his blockers.
“I feel that they’ll be fine,” Gore said. “We just need to clean up the small things and just play together. I like that (Singletary) is challenging these guys. We just need to get the M.E.s — the mental errors — out of the way.”
—Kory Sheets will get his chance, but it won’t be in a 49ers uniform. The Miami Dolphins signed him off the 49ers’ practice squad as a replacement for running back Patrick Cobbs, who is out for the season because of a knee injury.
An undrafted rookie from Purdue, Sheets packed his bags with mixed emotions. He was eager for his opportunity in the NFL but wished it could have been in San Francisco.
“I’ve been with these guys all training camp, and we went through the grind together,” Sheets said. “I’ve bonded with these guys. But this is just part of the business.”
Sheets ranks behind only Mike Alstott in Purdue history with 3,341 rushing yards. His 48 rushing touchdowns rank fifth on the all-time Big Ten Conference charts.
He had 39 carries for 177 yards (4.5 per carry) and three touchdowns during the preseason. The 49ers liked his running style but considered his other skills, such as pass protection, too raw. Sheets did not get promoted even with Gore out because of an ankle injury. The other backs on the roster are Glen Coffee, Moran Norris and Michael Robinson.
—Because of heavy rain, the 49ers conducted their morning walkthrough Tuesday at the Marriott hotel and spent their afternoon practice at Off The Wall Soccer, an indoor facility in Santa Clara.
Some of the players actually were bummed out that they didn’t get to go play in the rain.
“I would love to go play in this,” tight end Vernon Davis said. “There might be a game down the line where we have to play in this type of situation. “. . . But whether we’re inside or out, wherever we are we’re going to get better.”
—The 49ers re-signed Khalif Mitchell to the practice squad. Mitchell (6-foot-5, 318) has defensive-tackle experience, but the 49ers will work him on the offensive line.
—Isaac Sopoaga, a native of American Samoa, is teaming with countryman Joe Salave’a to raise money for tsunami victims back home.
Salave’a, the defensive-line coach at San Jose State, said three of his aunts and a cousin died when the tsunami struck the village of Leone.
“Guys like me and Isaac, we are just trying to do our part, whatever that may be,” Salave’a told 49ers.com.
