The San Francisco 49ers are known for their defense, but their ground game has also been a major factor in their success this season.

A big part of their rushing attack has been running back Matt Breida, who has missed the last couple of games with an ankle injury. However, the 49ers have gotten some good news on that front this week.

Per Josh Alper of Pro Football Talk, head coach Kyle Shanahan told reporters on Wednesday that Breida would be a limited participant in practice, a pretty significant step up after having not played in either of the previous two weeks.

Of course, Breida's status for the Niners' showdown with the Baltimore Ravens on Sunday remains up in the air, but he at least seems to be heading in a positive direction.

In the nine games he has played this season, Breida has rushed for 542 yards and a touchdown while averaging a robust five yards per carry. He has posted a pair of 100-yard performances, with the last one coming in Week 5 when he gashed the Cleveland Browns for 114 yards and his lone score of the year in a blowout win.

The 24-year-old, who played his collegiate football at Georgia Southern, went undrafted but eventually landed with the 49ers in 2017.

He had a decent rookie campaign, totaling 465 yards and a couple of scores on the ground while registering 4.4 yards per attempt, and last year, Breida showed marked improvement, recording 814 yards while reaching the end zone three times as a rusher, tallying 5.3 yards per tote.

San Francisco is an NFC-best 10-1 on the season.
