The 49ers and veteran running back Reggie Bush reached a contract agreement Saturday, he confirmed on social media.

"The best is yet to come #49ers," Bush wrote on his verified Twitter account. The contract is not signed, a source said, but the terms have been agreed upon.

Bush joins a 49ers backfield that includes Carlos Hyde, a second-round draft pick, and Kendall Hunter under contract for next season. Frank Gore, the team’s leading rusher in each of the past 10 seasons, signed a three-year contract this week with the Indianapolis Colts.

Bush was released by the Detroit Lions released on Feb. 25, so he will not count against the NFL's formula for compensatory draft picks. Bush played in 11 games last season due to a lingering ankle issue. Bush gained just 297 yards rushing in 2014, but he accounted for a career-high 1,512 yards from scrimmage in 2013 (1,006 rushing, 506 receiving). Bush, 30, a nine-year NFL veteran, entered the NFL as the No. 2 overall pick of the New Orleans Saints in 2006.

Bush visited Wednesday with 49ers coaches and officials at Levi’s Stadium in Santa Clara. After the meeting with Bush, 49ers GM Trent Baalke referred to him as a “great guy.” Bush also visited the New England Patriots on Friday.

“(We) got out of the visit what we needed,” Baalke said. “Now, it’s time to sit down and go through the pros and cons and try to make the best decision we can and he’ll have to make the best decision for him. He’s going to have options. We’re not the only team interested in Reggie Bush. I promise you that.”

On Wednesday, Baalke addressed the thought that the 49ers will lean more toward a running-backs-by-committee approach with Gore no longer in the organization. Hyde is likely to be the 49ers' running back on base downs, with Hunter and Bush incorporated as change-of-pace backs.

“As you look around the league, you see that more and more,” Baalke said. “This is tough. It’s tough to run 20, 30 carries a game in the NFL. My hat is off to the guys that are able to do that consistently, week-in and week-out through 16 games, taking the type of pounding that you take. So what you try to do is spread the wealth. Try to get through the season with your guys as healthy as you can, so when you get into that final stretch and, knock on wood, you’re making a run into the playoffs, you’ve got guys that are fit and able to play that 17th game, that 18th game, that 19th game.

“It’s tough. You look at today’s game compared to 20 years ago. It’s a different approach because there are a lot more personnel groupings that offenses are using to attack. It’s hard to find that one guy that can do all three (downs).”
