Running back Frank Gore looks at the history of the 49ers and realizes he is on the precipice of accomplishing something great. All that stands in his way are 22 yards and a cranky left ankle.

Gore can become the first player in 49ers history to rush for 1,000 yards in three consecutive seasons when the 49ers close out the season on Sunday against the Washington Redskins at Candlestick Park.

But Gore has been stuck on 978 yards since Dec.7 when he sustained an ankle sprain on the 49ers? first drive of the second half against the New York Jets. He took part Wednesday in his first limited practice since the injury.

?I?ll be upset if I can?t get it because of any injury,? Gore said. ?But I understand. I have more years. I really wanted to get it coming in. That was one of my goals.?

Gore currently ranks No. 5 on the 49ers? all-time rushing list with 4,383 yards. Joe ?The Jet? Perry tops the list with 7,344 yards.

Gore warmed up prior to the 49ers? game Sunday against the St. Louis Rams, but was inactive for the game. He said he had difficulty pushing off and creating any kind of burst.

?It would?ve been tough,? Gore said. ?I have to be able to protect myself on the field.?

?We?ll see how it feels,? 49ers coach Mike Singletary said. ?But we?re really going to try to keep our eyes on it and have him be honest and be smart about it.?

EXTRA POINTS

Former defensive lineman Bryant Young, who retired after last season, will be an honorary captain for Sunday?s game. The 49ers will don their ?throwback? uniforms.

The 49ers will not practice today because of Christmas. But Singletary asked all the players to take an hour during the day to prepare mentally for the game. The 49ers will return to practice on Friday.

When asked if there was any plan to get a youngster, such as safety Dashon Goldson, into the action for Sunday?s game, Singletary said no.

?I don?t want to just put guys in and (say) ?Let?s see what you have or whatever.? I have a pretty good idea of what we have,? Singletary said. ?I have a pretty good idea of who?s here. I don?t want to put someone out there at the expense of not winning the football game. I want to give us the best opportunity to win.?

Center Eric Heitmann and safety Michael Lewis sat out practice with abdominal strains but are expected to play Sunday. Cornerback Walt Harris and linebacker Takeo Spikes were given rest days. Gore and right tackle Adam Snyder (ankle) saw limited practice.
