San Francisco 49ers quarterback Alex Smith was back on the field and took full reps on Wednesday, according to the team's official injury report. Smith sustained a right finger injury in the 49ers' Week 5 contest against the Buffalo Bills.

Smith looks to be on track to play after injuring the middle finger on his throwing hand -- he was seen at the practice facility on Monday, which was a day off for the players. He is coming off a stellar performance against the Bills, throwing for 303 yards and three touchdowns in the 45-3 Niners victory.

Running back Brandon Jacobs also turned in a full practice, after a preseason knee injury saw him miss the first five games of the regular season. He practiced fully a week ago and could possibly have played, but was held out of the Week 5 game. If he turns in another full week of practice and does not suffer a setback, he should suit up on Sunday night against the New York Giants.

The only other injury to report was that of punter Andy Lee, who also practiced despite a hand injury. The 49ers' injury report looks clean everywhere else, and the team could have all of its players available in New York.
