The San Francisco 49ers are optimistic about the return of linebacker Dre Greenlaw for their Week 15 matchup against the Los Angeles Rams. After missing the entire season due to an Achilles' rupture suffered in the Super Bowl, Greenlaw has been participating in limited practices over the past two weeks. However, he was ruled out for the upcoming game against the Chicago Bears, indicating that while he is making progress, he is not yet ready to return to game action.

• Dre Greenlaw's potential return could bolster the 49ers' defense significantly.
• His recovery from a serious injury has been closely monitored, and limited practices show positive signs.
