SANTA CLARA, Calif. (AP) - Frank Gore quickly gave credit to rookie LaMichael James for an impressive NFL debut - and for taking some pressure off the three-time Pro Bowler in the process.

Anthony Dixon is doing his part for San Francisco, too.

The 49ers' versatile running game showed its depth in Sunday's 27-13 victory against Miami, with Gore leading the way en route to his sixth career 1,000-yard rushing season.

It sure doesn't appear as though Brandon Jacobs will be back in the mix the rest of the way - barring an injury, of course - after he became increasingly verbal in his frustration via social media during the weekend over a lack of playing time. He referenced being ``on this team rotting away.''

Coach Jim Harbaugh declined to address Jacobs' comments on Monday, even when asked whether Jacobs is still on the team. He said he was invoking his ``fifth amendment'' right.
